TPS40400RHLT TI PMBus Controller | 24-VQFN (5.5x3.5) | 4.5V-20V, 600kHz

Product Overview

The TPS40400RHLT is a PMBus-compliant synchronous buck controller from Texas Instruments, designed for high-efficiency, low-voltage power conversion. It operates from a 4.5V to 20V input supply and provides a programmable output voltage down to 0.6V with ±1% accuracy. The device integrates a PMBus interface for telemetry and control, enabling real-time monitoring of voltage, current, temperature, and fault conditions. Housed in a compact 24-VQFN (5.5x3.5mm) package, it is ideal for space-constrained applications requiring precise power management.
