11. PM3533 Overview
1 Overview
PM3533 is RF energy management and RF FE control device that contains following
functionalities: SMPS (Switched Mode Power Supply), Boost DC-DC converter, Buck DC-
DC converter, several regulators for internal use and one regulator for external use.
PM3533 also contains two antenna control IOs and two PA bias DAC outputs with the
possibility to use the second DAC output also as third GPIO.

1.1 Main features
• Antenna controls and PA control signals
– Two antenna-tuning controls. Controls are programmable via the Serial Peripheral
Interface (SPI).
– One adjustable current reference for PA, with two multiplexed outputs.
– One of the outputs can also be used a static control output
• SMPS converter
– SMPS converter optimized for both GSM and WCDMA power amplifiers
– GSM mode bursts ramp-up/ramp-down capability
– Two different operating modes, which are controlled via Serial Peripheral Interface
(SPI). The operating modes are used to optimize SMPS efficiency at lower power
levels. Operation modes are explained in Section 1.1.1.
– Internal adjustable switching clock
– Dithering. Dithering adds deviation to switching frequency, which lowers switching
harmonic at output of SMPS. The deviation of the dithering is adjustable between
two different frequencies.
– Adjustable delay control for SMPS power switch drivers.
– Adjustable integrated loop-filter.
• Boost DC-DC converter
– Boost DC-DC converter regulates the battery voltage up to 4.0 V, 4.3 V, 5.3 V or
6 V.
CD00271682 Rev 3 11/77
12. Overview PM3533
– Three different operating modes are controlled by the Serial Peripheral Interface
(SPI). The operating modes are used to optimize the power converter efficiency at
lower power levels. The operation modes are explained in Section 1.1.1.
– Sampled soft-start, to enable smooth transient behavior on Boost DC-DC
converter output when starting the device or to continue from earlier idle (with its
output already at the correct level)
– Internal adjustable switching clock.
– Dithering. Dithering adds deviation to switching frequency, which lowers switching
harmonic at the output of the boost DC-DC converter. The deviation of the
dithering is adjustable between two different frequencies
Information classified Company restricted - Do not copy (See last page for obligations)
• Buck DC-DC converter
– The buck DC-DC converter down-regulates the battery voltage to 1.45 V.
The output voltage is adjustable also to 1.65 V or 1.35 V, another normal usage
set is 1.85 V or 1.55 V.

output when starting the device or to continue from earlier idle (with its output
already at the correct level).
– Internal adjustable switching clock.
– Dithering. Dithering adds deviation to switching frequency, which lowers switching
harmonic at the output of the buck DC-DC converter. The deviation of the dithering
is adjustable between two different frequencies.
• External regulators
– PM3533 has one regulator for external use. VHI regulates the battery voltage to
2.6 V or 2.5 V. VHI is enabled automatically after power-up with default output
voltage of 2.5V.
• Multiplexer
– PM3533 has one programmable multiplexer used to switch several analog node
voltages to PM3533 MUX1 I/O. The battery-monitoring block is also connected to
the multiplexer. Additionally MUX1 I/O can be used for self-testing
purposes.Multiplexer structure is shown in Figure 22.
• Serial Peripheral Interface (SPI) for PM3533 control.
• Battery monitoring block. This block enables battery voltage monitoring during the
operation and can also be used for self-testing purposes in production line.
• Under Voltage Lockout block. This block adds special protection by automatically
powering-down the boost power converter if abnormal power-downs occur at full power
mode.
• 40-bit OTP memory. One time programmable memory is needed to switch the
frequency tuning for all three converters. Also TSD (Thermal shutdown cell) can be
tuned with OTP memory.
• Thermal shutdown
– Thermal shutdown circuitry monitors the die temperature and fulfills a shutdown
when a specified temperature is reached. Thermal protection is enabled
automatically after power-up.

13. PM3533 Overview
1.1.1 Special power saving modes
DCDC converters have “low power” operation modes, which reduce the current
consumption in low power mode. The modes are controlled through the serial control
interface.
SMPS converter
1. “Low power” mode means that the size of power switches including the drivers are
reduced at lower power levels.
2. Power switches are divided into two parts. In high power levels both parts are used
Information classified Company restricted - Do not copy (See last page for obligations)
while in low power levels only 1/3 part of the switches and their drivers are used. The
decision on which mode is used comes from the base-band.
Boost DC_DC converter
Boost DC_DC converter includes two different power saving modes.
Company restricted
1. “Full power” mode means that the boost DCDC converter at normal operational mode
with the full output power capability. Enabling of this is coming from the base-band.
2. The boost converter has also a “By-Pass” mode, which corresponds to 100% duty
cycle operation. In that mode the converter upper switch is turned on while the
converter lower switch is turned off. The boost by-pass function can be used in low
power levels by shutting down the boost-converter.
