LM25011MY/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM25011MY/NOPB is a high-voltage synchronous buck switching regulator manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 42 V and delivers up to 2 A of output current. The device utilizes constant-on-time (COT) architecture for fast transient response. Key electrical parameters include a fixed switching frequency of 2.25 MHz, adjustable output voltage from 2.51 V to 40 V, and a typical quiescent current of 1.2 mA. It functions within a temperature range of -40°C to +125°C and is housed in a 10-pin HVSSOP package.
