DC781A

Product Details

Demonstration circuit 781 is a Telecom DC/DC converter featuring the LTC3803ES6 constant frequency current mode flyback controller. The DC781 converts 36V to 72V input to 3.3V or 5V output and provides 2A of output current. The 200kHz constant frequency operation is maintained down to zero load which prevents low frequency noise that occurs when power converters operate in pulse skipping mode. The converter provides high output voltage accuracy (typically ±2%) over wide load range with no minimum load requirement.
