RT5112
Smart Power-Management Integrated Circuit for Camera
Module Application
General Description
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
2
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.
