TPS65400RGZR General Description

The TPS65400RGZR is a versatile Power Management Unit designed for compact applications that demand high efficiency and reliability. This integrated PMU boasts a single-stage conversion design that eliminates the need for extra cooling, making it ideal for space-constrained environments with elevated operating temperatures. Its four high-current buck switching regulators provide up to 4A output current for SW1 and SW2, and 2A for SW3 and SW4. With an input voltage range of 4.5 to 18V and an output range of 0.6V to 90% of VIN, the TPS65400RGZR offers flexibility for a variety of system requirements

Key Features

Suitable for applications requiring multiple power rails
Fast response to changes in input voltage and current
Error-free operation with automatic recovery from fault conditions
