SPSA068-TR ST Power Management IC | 32-QFN(5x5) | 3A Output, 2.5V-5.5V Input

Product Overview

The SPSA068-TR from STMicroelectronics is a high-efficiency, synchronous step-down (buck) regulator designed for space-constrained applications. Housed in a compact 32-QFN (5x5) package, it delivers up to 3A continuous output current from a 2.5V to 5.5V input supply. The device integrates low RDS(on) power MOSFETs and features a fixed switching frequency of 1.5MHz, enabling small external components. With excellent load and line regulation, the SPSA068-TR is ideal for powering core voltages in networking, industrial, and automotive systems.
