DC Switching Voltage Regulators

LM25010SD Description

The LM25010SD from Texas Instruments is a 1A adjustable buck switching regulator designed for high-efficiency step-down voltage conversion. Housed in a compact 10WSON package, it supports a wide input voltage range of 6V to 42V, making it suitable for industrial, automotive, and telecom applications. The output voltage is adjustable from 2.5V to 37V, providing flexibility for diverse power supply requirements. With a switching frequency range of 100kHz to 1MHz, it balances efficiency and component size, enabling optimized designs. This non-synchronous buck converter is obsolete but remains relevant for legacy systems due to its robust performance and reliability.
