System PMIC for Battery Powered Systems BD71805MWV General Description The BD71805MWV is a single chip power management IC for battery-powered portable devices. It integrates 4 Bucks, 3 LDOs, 2A single-cell linear charger, OVP, Coulomb counter, RTC, 32 kHz crystal circuitry and 3 GPOs. Four highly efficient 2.5MHz step-down converters supply power to the application processor as well as system peripherals such as DDR memory, wireless modules, and touch controller. The regulator to the processor core supports DVS. The regulators maintain high efficiency over a wide range of current loads by supporting both PFM and PWM modes. High switching frequency allows the use of smaller and cheaper inductors and capacitors.
