STEVAL-ISA204V1

STEVAL-ISA204V1 is an evaluation board designed to demonstrate high efficiency DC-DC conversion, able to output 100W (5V/20A) from 42 to 56V DC input, which is especially suitable for telecom applications. The power conversion stage is based on an active clamp forward topology managed by a PM8804 PWM controller featuring all the integrated circuitry necessary for a compact and efficient 48V converter. The highly configurable controller includes a programmable oscillator for switching frequency regulation up to 1MHz, adjustable slope compensation, dual complementary low-side drivers with programmable dead time, programmable soft start, soft turn off and a programmable current sense blanking time.

• DC-DC forward converter based on PM8804
• Switching frequency of 250kHz
• Peak efficiency greater than 94%
• Open circuit protection
