The ISL6726EVAL1Z evaluation board is a 48V input to 5V output DC/DC converter that can output current up to 40A.

The ISL6726EVAL1Z board uses the ISL6726, an advanced current mode PWM controller, to implement control of an active clamp forward. The circuit operates at fixed frequency with peak current control mode. To get high efficiency, the converter adopts a synchronous rectifier to replace the diode rectifier.
