产品详情

Demonstration circuit 1031A-B is a 36V-72Vin, synchronous forward converter featuring the LTC3725 forward converter and the LTC3726 secondary-side controller. This circuit was designed specifically to attain a high current, low ripple, synchronously rectified forward converter to efficiently power 3.3V loads at up to 20A from a typical telecom input voltage range. This circuit features secondary side control of the supply eliminating the need for an optocoupler.
