TPS40055PWP TI PWM Controller | 16-HTSSOP | 4.5V-15V Input, 1MHz

Product Overview

The TPS40055PWP from Texas Instruments is a high-performance, wide-input synchronous buck controller designed for low-voltage, high-current power conversion. It operates from a 4.5V to 15V input supply and provides a regulated output voltage as low as 0.7V with ±1% accuracy. The device features a fixed-frequency voltage-mode control architecture with a programmable switching frequency up to 1 MHz, enabling compact power supply designs. Housed in a 16-pin HTSSOP package with PowerPAD for enhanced thermal performance, the TPS40055PWP is ideal for space-constrained applications requiring high efficiency and reliability.
