RT5133

Integrated PMIC with 8-Channel LDOs and 3 GPOs for Camera Module Applications

RT5133
New

The RT5133 is a highly-integrated power management IC, which includes 8 LDOs for camera sensor applications, including 2-Ch DVDD, 4-Ch AVDD, 1-Ch VIO, 1-Ch VAF and 3 GPOs for portable devices.

The output voltages, soft-start time and protections of regulators can be controlled by writing the registers through I2C.

The LDO1 can be used to supply power to IO (VIO). The LDO2 can be used to supply power to auto focus unit (VAF). The LDO3 to LDO6 can be used to supply power to AVDD. The LDO7 and LDO8 can be used to supply power to DVDD.

3 GPO output pins can control external device or be reused for another purpose.

The RT5133 is available in a WL-CSP-25B 1.84x1.84 (BSC) package.
