Broadcom Corporation - BCM59035 - Mobile Power Management Unit

The BCM59035 Power Management Unit (PMU) is a highly integrated complete Power Management and Battery Management solution optimized for EDGE, WEDGE, and HSDPA chip sets. The BCM59035 contains a fully featured, host-independent wall and USB linear charger for Li-ion/Li-polymer batteries, USB OTG VBUS Regulator and Comparators two high-efficiency synchronous buck Regulators fifteen high-performance LDOs a backup Battery Charger a Real-Time Clock two programmable current sources (PWMLEDs) to power up LEDs two GPIO ports, and a fuel gauge. The BCM59035 CAN be controlled via a 100-/400-kHz IC-compatible (BSC) Interface An external host controller CAN access BCM59035 BSC Registers to read or program the internal blocks. The two Switching Regulators (switchers) provide power to the core and I/O circuit blocks of the Baseband IC. The regulators' operating modes and output voltages are configurable via BSC to adapt to the phone's various operating states, enabling optimum efficiency over the entire load range with up to 93% during normal load. The core switcher supports open loop dynamic voltage scaling (DVS) through BSC, which further improves the system's efficiency. The switching regulators' operating frequency is 2 MHz, allowing the use of small-size, low-profile external components.
