BCM59001 - Mobile Power Management Unit

Mobile Power Management Unit

The BCM59001 is a highly integrated and complete power management solution specifically designed for midrange Li-Ion- or Li-Pol-powered cellular handsets.

This device implements advanced power management including two highly efficient switching regulators for core and I/O supply and 11 high-performance LDOs with ECO mode. The peak efficiencies of the switching regulators are 93% and ~83% at 1 mA low-power mode. A switching frequency of 2 MHz enables small 2.2-μH inductors and 4.7-μF output capacitors. The output voltage of both switching regulators and the LDOs are I²C-programmable in 100-mV steps.

  • Two 300-mA switching regulators with programmable output voltages and low-power mode of 50-μA quiescent current
  • Multimode buck switchers to achieve high efficiency with 93% peak efficiency in PWM mode and approximately 83% efficiency at 1 mA in low-power mode
  • High level of integration reduces the power and battery management bill of materials
  • Multimode buck switchers offer best-in-class efficiency
