TPS40074RHLR TI PWM Controller | 20-VQFN (3.5x4.5) | Wide Vin 4.5V-15V, 1MHz

Product Overview

The TPS40074RHLR is a high-performance, synchronous buck controller from Texas Instruments, designed for efficient voltage regulation in demanding applications. It operates over a wide input voltage range of 4.5V to 15V and delivers output voltages as low as 0.7V. Housed in a compact 20-pin VQFN package (3.5mm x 4.5mm), it integrates advanced features such as voltage feed-forward, programmable soft-start, and frequency synchronization up to 1 MHz. This controller is ideal for point-of-load (POL) converters, telecom infrastructure, and industrial systems requiring high efficiency and small footprint.
