  11. 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. Figure 5. PM3533 functional block diagram Information classified Company restricted - Do not copy (See last page for obligations)Company restricted 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.

  12. 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. – Sampled soft-start, to enable smooth transient behavior on Buck DC-DC converterCompany restricted 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. 12/77 CD00271682 Rev 3
  13. 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.
