UCC25230 PWM Converter

Texas Instruments' 12 V to 105 V input, 0.2 A output switching converter

Texas Instruments' UCC25230 is a highly integrated PWM converter operating as an isolated forward flyback. It has integrated high-side and low-side power switches and the control circuit includes all key converter functions. The power stage requires only one multiple winding coupled inductor and a few output capacitors for the complete solution. Voltage-mode feed-forward control with external compensation allows optimal output filter selection over a wide input voltage range. The UCC25230 has fixed frequency set internally at 380 kHz. It also includes input voltage UVLO and OVLO comparators with hysteresis as well as an input-good, open-collector output signal which can be used to enable PWM controllers. UCC25230 Datasheet

Evaluation Module

Texas Instruments Part Number	Digi-Key Part Number	Description
UCC25230EVM-754	296-30213-ND	This EVM is to help evaluate the UCC25230 PWM device in a forward-flyback or flyback DC-to-DC converter topology for a 48 V telecom biasing supply. The targeted application is telecom module design with nominal 48 V input. The EVM is a dual-output converter. Each channel is nominal 12 V and 65 mA for a total output power of 1.5 W. The design is made on a small footprint and low profile, the effective circuit area for the bias portion is 0.6" x 0.5" x 0.15" (L x W x H).
