System PMIC for i.MX 7Solo/7Dual

BD71815AGW is a single-chip power management IC for battery-powered portable devices. The IC integrates 5 buck converters, 8 LDOs, a boost driver for LED, and a 500mA single-cell linear charger. Also included is a Coulomb counter, a real-time clock (RTC), a 32 kHz crystal oscillator and a general-purpose output (GPO).
The IC’s buck converters supply power to the application processor as well as system peripherals such as DDR memory, wireless modules, and touch controllers. These regulators maintain high efficiency over a wide range of current loads by supporting both PFM and PWM modes. They also operate at a high switching frequency of 6MHz, which allows the use of smaller and cheaper inductors and capacitors. The regulator supplying the processor core also supports Dynamic Voltage Scaling (DVS).
