LT8631 Datasheet 1A Synchronous Micropower Step-Down Regulator

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LT®8631 is a current mode PWM step-down DC/DC converter with internal synchronous switches that provide current for output loads up to 1A.

The wide input range of 3V to 100V makes the LT8631 suitable for regulating power from a wide variety of sources, including automotive and industrial systems and 36V to 72V telecom supplies.

Low ripple Burst Mode operation enables high efficiency operation down to very low output currents while keeping the output ripple below 10mVP-P.
