L4960H

L4960H Description

The L4960H from STMicroelectronics is a monolithic buck switching regulator designed for high-efficiency step-down voltage conversion. This adjustable output regulator delivers up to 2.5A of continuous output current with an input voltage range of 9V to 46V and an output voltage adjustable from 5.1V to 40V. Operating at a switching frequency of 100kHz to 150kHz, it employs a non-synchronous buck topology, making it suitable for medium-power applications requiring stable, high-current outputs. Packaged in a 7-HEPTAWATT through-hole tube, the L4960H is RoHS3 compliant and REACH unaffected, ensuring environmental compliance.

L4960H Features
