RT5142

Power Management Unit Total Power Solution for SSD

The RT5142 offers highly-integrated multi-channel system power management solutions to meet the performance, efficiency, and feature requirements.

The RT5142 incorporates four buck regulators and two LDOs that deliver several output voltages. This provides flexibility to support applications of different VIDs with a configurable power-on sequence.

The RT5142 supplies 8 configurable GPIOs for system hardware control requirements. These GPIOs can be configured for multiple purposes, such as, PWRDIS/ Sleep/ Deep Sleep settings for PMIC state machine control, Buck1/2 Enable/Disable setting, Buck3/4 VID control setting, POR_RST_N pin for monitoring PMIC power good and can also be configured as two sets External_EN and External_PG signals. In addition, the GPIOs also support three-state through I²C interface configuration when the RT5142 works in the normal mode.
