LTC3806
Synchronous
Flyback DC/DC Controller U FEATURES DESCRIPTIO ■ The LTC®3806 is a current mode synchronous flyback
controller that drives N-channel power MOSFETs and
requires very few external components. It is intended for
medium power applications where multiple outputs are
required. Synchronous rectification provides higher efficiency and improved output cross regulation than
nonsynchronous converters. ■
