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 in x 0.5 in x 0.15 in (L x W x H). The UCC25230 is a highly integrated PWM controller operating as an isolated forward flyback. It has integrated high-side and low-side power switches and a control circuit with all key converter functions included. 2 Description The EVM is a 1.5-W forward-flyback DC-to-DC converter that accepts an input range of 36 V to 72 V DC and converts it to two regulated output voltages, nominally 12 V and maximum 65-mA load current for each channel. The two outputs are 1500-V level isolated from each other, with one channel on the primary side and the other on the secondary side. 2.1 Typical Applications • • • • • 2.2 Features • • • • • • • • 2 Biasing Power to Power on the Main Controller (whether on the primary or the secondary side of the isolation barrier) 48-V Telecom Server Systems Datacom DSP’s, ASIC’s, and FPGA’s Start Up Directly from Telecom Input Voltage 36 V to 72 V DC Two Regulated 12-V Outputs, 65-mA Maximum Load Current Telecom Isolation from Primary-to-Secondary 1500 V Small Footprint and Low Profile Design Output Voltage Regulation (from no load to full load, and from low line to high line) Input Voltage Status Signal, (manually or automatically set up) Device Evaluation Test Points All Surface Mount Components and Industry Leading-Edge Small Footprint 1.5-W Forward-Flyback DC-to-DC Converter for 48-V Telecom Biasing Supply Copyright © 2011, Texas Instruments Incorporated SLUU670 – November 2011 Submit Documentation Feedback Electrical Performance Specifications www.ti.com 3 Electrical Performance Specifications Table 1.

You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials. Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch.
