Low Power Design Techniques for ASIC / SOC DesignRajesh_navandar
1. Low power techniques aim to reduce both dynamic and static/leakage power in integrated circuits. Dynamic power is reduced through techniques like lowering supply voltage and clock frequency, while leakage power is reduced by increasing transistor threshold voltage.
2. Power gating is a widely used technique that temporarily turns off unused circuit blocks to drastically reduce leakage power. It requires additional power switches and isolation cells to safely turn blocks on and off.
3. Multi-threshold CMOS uses both low and high threshold voltage transistors optimized for performance and leakage respectively. Further scaling presents new challenges as leakage power becomes dominant.

The PI33XX: Zero-Voltage Switching Applied to Buck RegulationVicor Corporation
The Picor PI33XX Cool-Power® ZVS Buck Regulator Series delivers maximum power density and high efficiencypoint of load DC-DC regulation. This unique, high density, buck regulator integrates a high performance Zero-Voltage switching (ZVS) topology along with power and support components all within a surface mount package.

The Intermediate Bus Architecture uses an AC front end power supply to deliver a DC output voltage, typically -48V, to an Intermediate Bus Converter. The IBC provides isolation and conversion to a lower intermediate bus voltage like 9.6V or 12V. This intermediate bus voltage then powers downstream non-isolated regulators that provide regulated voltages for electronic loads. Benefits include lower cost, higher efficiency and power density, and addressing the need for multiple low-voltage outputs. Common applications include enterprise networks, data storage, telecom equipment, and wireless networks.
Distributed power architecture (DPA) is a decentralized power distribution approach that addresses limitations of centralized power systems. It consists of AC-DC converters located at the mains entry serving DC-DC converters located on system boards or near points of load. Benefits include leveraging modular, high-density DC-DC converters; addressing demands for flexibility; and providing higher reliability, hot-swap accessibility, and lower maintenance costs. DPA places DC-DC converters close to points-of-load to reduce noise, improve regulation, and simplify fault tolerance.
The document describes different power distribution architectures for server and networking equipment. It proposes a Controlled Bus Architecture where the backplane voltage is held constant, allowing bus converters to operate at higher efficiency with a narrow input voltage range. This approach offers higher distribution and converter efficiency, easier interfacing of power sources, and increased board density compared to an unregulated Intermediate Bus Architecture with a wide voltage range. The cost is an additional regulation stage for backup power systems.
VI BRICK Intermediate Bus Converter Module (IBC) module is a very efficient, low profile, isolated, fixed ratio converter for power system applications in enterprise and optical access networks.
Picor integrated Cool-ORing product takes advantage of two different technologies combining a 1.5 mΩ on-state resistance (RDS(on)) single N-Channel MOSFET with high density control circuitry.
Vicor Corporation, located in Andover, Massachusetts, designs, manufactures and markets modular power components and complete power systems used in the communications, data processing, industrial controls, test equipment, medical and defence electronic markets.

NIMA2024 | De toegevoegde waarde van DEI en ESG in campagnes | Nathalie Lam |...BBPMedia1
Nathalie zal delen hoe DEI en ESG een fundamentele rol kunnen spelen in je merkstrategie en je de juiste aansluiting kan creëren met je doelgroep. Door middel van voorbeelden en simpele handvatten toont ze hoe dit in jouw organisatie toegepast kan worden.
2. VI Chip Regulator Module (PRM)
› Non-isolated ‘Buck-Boost’ topology
› Fixed, high frequency (~1.3 MHz)
› Efficiency up to 97%
› Wide input range to regulated output
– Commercial:
› Input voltage:
18 – 36 V, 18 – 60 V, 38 – 55 V, 36 – 75 V
› Output voltage: 26 – 55 V, 5 – 55 V
› Output power:
120 W, 170 W, 200 W, 240 W, 320 W, 400 W
– MIL-COTS:
› Input voltage: 16 – 50 V
› Output voltage: 26 – 50 V
Full-chip: 1.28” x 0.87” x 0.265” › Output power: 120 W
Half-chip: 0.65” x 0.87” x 0.625”
› Usage
– Upstream regulator for a downstream VTMs
– Stand-alone, non-isolated regulator

3. Value Proposition: Power Density
› High power density enables:
– More functions (Gbps, ports, flops, capacity) in the same space
– A more powerful system without a larger power supply
– A more powerful system without a heavier power supply
› VI Chip power density enables:
– Systems that would be impossible with conventional approaches
– Systems that would be too large, too heavy or not cost effective
with a conventional approach
› VI Chips decrease power footprint by 40% today
› Power density increase of 25% every 2.5 years

4. Value Proposition: Efficiency
› High efficiency enables:
– Smaller, cooler, quieter systems
– Energy cost savings for end user
– High performance systems with minimal total cost of ownership
› VI Chip architectures reduce hidden power losses
– A “whole system approach”, not just a focus on one conversion stage
› VI Chip technology continues to raise the efficiency standard
– IBC has half the power loss compared to industry IBC average.
– Alternative solutions are at the technological limit with
respect to efficiency improvements
– New Vicor products cut losses by 20% every 2.5 years

5. Value Proposition: Flexibility
› Flexibility enables:
– Re-use of power components
in multiple products
– Fewer SKUs, higher volume,
lower cost
– Fast time to market
– Reduced development effort
› VI Chip technology reduces the need
for custom power systems
– Power component paradigm
› Expanding portfolio of products
increases flexibility over time
– More options, more configurability,
less complexity, shorter design time

6. Factorized Power Architecture
› Definition: Factorized Power is…
– The separation of Regulation, Isolation, and voltage Transformation functions
typically contained together within a “brick” DC-DC converter
› Components:
– Small, highly efficient, flexible, building blocks called “VI Chips”
› PRM – Pre Regulation Module
› VTM – Voltage Regulation Module
› BCM – Bus Converter Module
› Advantages:
– Reduces the physical area and volume space of the power converters
– Reduces power dissipation at the Point of Load
– Reduces distribution losses
– Eliminate unnecessary converter functions to improve system efficiency

7. 48 V Factorized Bus Architecture (FPA)
› Intermediate Bus Architecture (IBA)
– e.g., 48 – 12 V bus converters, then 12 V – 1.x V buck regulators
– Trade-off between I2R distribution loss and buck duty cycle
– Load <1 V means <10% duty cycle
– FET peak voltage much higher (>12 V) than load voltage (1 V)
› Factorized Power Architecture (FPA)
– Pre-regulators (PRM), then Current Multipliers (VTM)
– Efficient power distribution (48 V)
– Load <1 V with ~ 100% VTM duty cycle
– FETs are low voltage (e.g., 3 V) so low RDS(ON)
and high performance Full-chip
› Benefits of current multiplication at the load Up to 130 A
1.28 x 0.87 x 0.265 in (1.1 in2), 0.5 oz
– Fast transient response 3.25 x 2.2 x 0.67 cm (7.2 cm2), 15 g
– No bulk capacitors Half-chip
Up to 200 W
– High density 0.64 x 0.87 x 0.265 in (0.55 in2), 0.25 oz
1.63 x 2.2 x 0.67 cm (7.2 cm2), 8 g
– High efficiency
– High PoL functionality

8. Wide (11:1) Trim Range
› Extreme trim range with simple, small system
– Use K = ¼ for 1.25 – 13.75 V range
– Use K = 1/40 for 0.125 – 1.375 V
