TPS62619YFDR TI Step-Down Converter | 6-DSBGA | 3MHz, 800mA

Product Overview

The TPS62619YFDR from Texas Instruments is a high-efficiency, synchronous step-down DC-DC converter optimized for battery-powered and space-constrained applications. Housed in a compact 6-pin DSBGA package (0.9mm x 1.3mm), it delivers up to 800mA output current with a 3MHz switching frequency, enabling small external components. The device operates from a 2.3V to 5.5V input voltage range and provides a fixed output voltage of 1.8V with ±2% accuracy. Advanced features include forced PWM and auto PFM/PWM modes for high efficiency across load ranges, output voltage discharge, and over-temperature protection.
