The RT5112 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 I<SUP>2</SUP>C interface. The output voltage OVP/UVP, OCP and OTP protection are built in the RT5112. The RT5112 is available in a WL-CSP-25B 2.2x2.3 (BSC) package.
