O31310QRWGRQ1 General Description

The TPS65313-Q1 device is a power management IC (PMIC) that meets the requirements of MCU-controlled or DSP-controlled automotive, industrial, machinery, or transportation systems. With the integration of commonly used features, the device helps reduce board space and system cost.

The device includes one wide-VIN synchronous buck regulator (BUCK1) combined with one low-voltage (LV) buck regulator (BUCK2) and one boost converter (BOOST), which are powered from the wide-VIN buck regulator (BUCK1). The device features a low quiescent current in the OFF state to reduce current consumption in case the system is permanently connected to the supply. All outputs are protected against overvoltage, overload, and overtemperature conditions.
