UCC35705EVM [Texas Instruments]

UCC35705EVM is a 48-V to 3.3-V RCD Forward converter with UCC35705 voltage-mode control and self-driven synchronous rectification. It features a full range telecom input (36 V to 72 V DC), 3.3 V at 10 A output (33 W), 1500-V isolation, and operates at 500 kHz. The EVM uses a single TPS2829 driver and includes optically isolated voltage mode control with voltage feed-forward, peak-by-peak current limit protection, low input voltage protection, RCD transformer reset clamp, and an externally programmable soft-start circuit. The board is business card sized (2.0” x 3.5”) and achieves up to 85% efficiency.
