Smart Power-Management Integrated Circuit for Camera Module Application

RT5112

Update Alert Share

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 I2C 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.
