# TPS62133RGTT (Component)
## Description
Buck Switching Regulator IC Positive Fixed 5V 1 Output 3A 16-VFQFN Exposed Pad
TPS62133RGTT is a synchronous step-down DC-DC buck converter from Texas Instruments designed for high-efficiency power regulation in compact embedded and battery-powered applications. It integrates high-side and low-side MOSFETs and operates with a fixed switching frequency optimized for low EMI and minimal external component count. The device supports wide input voltage operation and delivers stable regulated output voltage with excellent transient response and high conversion efficiency across varying load conditions.
This regulator is commonly used in portable electronics, industrial controllers, wireless communication modules, sensor systems, and low-power embedded designs where compact PCB footprint and efficient power conversion are critical. The integrated soft-start, thermal shutdown, overcurrent protection, and power-good monitoring features improve system reliability and simplify power supply implementation.
The TPS62133RGTT is housed in a compact QFN package suitable for space-constrained designs and supports operation with ceramic input and output capacitors for improved stability and reduced BOM size.
