BD71805MWV

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. Features  4 Buck Converters: - 1-2000mA Buck - 3-1000mA Bucks  3 LDOs (General purpose) - 3-300mA LDOs  LDO for DDR Reference Voltage  LDO for Secure Non-Volatile Storage (SNVS)  Single-cell Linear LIB Charger with 30V-OVP - Selectable Charging Voltage : 3.72 to ...
