The Texas Instruments UCC25230EVM-754 evaluation module (EVM) helps designers evaluate the UCC25230 PWM IC in a forward-flyback DC-DC converter topology for a 48V telecom biasing supply. The targeted application is telecom module design with nominal 48V input. The EVM is a dual-output converter. Each channel is nominal 12V and 65mA for a total output power of 1.5W. The design offers a small footprint and low profile. The UCC25230 is a highly integrated PWM controller operating as an isolated forward-flyback, . The UCC25230 has integrated high-side and low-side power switches and a control circuit with all key converter functions included.
