US3463 Datasheet
  

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.

 

FEATURES

* PSR Mode

* Light Load Frequency Reduce

* Low Startup Current

* Leading-Edge Blanking

* Peak Current Mode

* Cycle by Cycle Current Limit

* Under-voltage Lockout

* Soft Start

* VCC Over Voltage Protection

* Output Short-Circuit Protection

* Output Over Voltage Protection

* Over Current Protection

* Over Temperature Protection
