A Compact 36-72V DC Input, 3.3V-10A Output Power Supply

Advertisements

The output of this power supply is an isolated 3.3V/10A output, produced from an input is 36-72V DC. Airflow is required at higher ambient temperatures to get the full rated power.

The topology used is a single transistor forward, with a reset winding on the transformer to reset the core. The maximum duty cycle is less than 50%. The design uses the MAX5052A PWM controller.
