PRIMARY SIDE DC/DC CONTROLLER

DESCRIPTION

The UTC US3463 is an Ethernet powered (Power over

Ethernet, PoE) DC/DC controller. It integrates a 200V power

MOSFET with PSR control. It is suitable for Flyback topology,

providing accurate CV control loop, high system efficiency and

good EMI characteristic.
