LT8471 - Dual Multitopology DC/DC Converters

General Description

The LT®8471 is a dual PWM DC/DC converter containing two internal 2A, 50V switches and an additional 500mA switch to facilitate step-down and inverting conversion.

Each 2A channel can be independently configured as a buck, boost, SEPIC, flyback or inverting converter.

Key Features
