TPS62315YZR TI Step-Down Converter | 8-CSP | 3MHz, 500mA

Product Overview

The TPS62315YZR from Texas Instruments is a high-frequency, synchronous step-down DC-DC converter optimized for battery-powered portable applications. Housed in a compact 8-pin CSP package (0.8mm pitch), it delivers up to 500mA output current with excellent efficiency. The device operates at a fixed 3MHz switching frequency, enabling the use of small inductors and capacitors, thus minimizing solution footprint. Input voltage range is 2.5V to 6.0V, making it suitable for single-cell Li-Ion or multi-cell alkaline/NiMH batteries. Output voltage is adjustable from 0.6V to VIN via external resistors. The TPS62315YZR features power-save mode for light-load efficiency, 100% duty cycle for low dropout, and integrated active discharge. Protection includes overcurrent and thermal shutdown.
