The RT5112H device is a smart power management IC which includes a low-quiescent-current HCOT Buck converter, a ACOT Boost converter and four high PSRR low dropout regulators (LDO). One can control the channel power sequence, output voltage level and DVS slew rate by setting registers via I2C interface. The output voltage OVP/UVP, OCP and OTP protection are built in the RT5112H. The RT5112H is available in a WL-CSP-25B 2.2x2.3 (BSC) package.
