Introduction

Small, high efficiency DC/DC converters are critical to the design of leading-edge electronics. Achieving high accuracy and efficiency traditionally means adding extra components, complexity, and size. Not so with the LT3837. This flyback controller serves 10W to 60W isolated applications with high performance, simplicity, small size, and a minimum component count.

High efficiency controller capabilities

The LT3837 operates from a 4.5V to 20V input, but the converter ...
