The L4962 is a monolithic power switching regulator that delivers 1.5A at a voltage variable from 5V to 40V in step-down configuration. Features of the device include current limiting, soft start, thermal protection, and 0 to 100% duty cycle for continuous operating mode.
The L4962 is a monolithic step‑down switching regulator delivering up to 1.5 A with an adjustable output voltage from 5.1 V to 40 V. It integrates current limiting, soft‑start, thermal shutdown and operates at switching frequencies up to 150 kHz, achieving efficiencies up to 90% while requiring very few external components.
The device is offered in a 16‑lead Powerdip (12+2+2) package and a Heptawatt package. Detailed pin functions, absolute maximum ratings, electrical characteristics, and mechanical dimensions are provided for designers to implement the regulator in a variety of applications.
