The STEVAL-ISA203V1 evaluation board is designed to demonstrate a highly efficient DC/DC conversion with 60-W output (12 V/5 A) from 42- to 56-VDC input (48 V nom.), which is particularly suitable for telecommunications applications. The power conversion stage is based on a flyback topology managed by the PM8804 controller, which contains all the integrated circuits required for a compact and efficient 48-V converter. The highly configurable controller includes a programmable oscillator for switching frequency regulation up to 1 MHz, adjustable slope compensation, dual complementary low-side drivers with programmable dead time, programmable soft start, soft switch-off and a programmable current sensor blanking time. The secondary side uses the SRK1000 adaptive synchronous rectification controller for flyback converters. https://elecena.pl/product/26049388/steval-isa203v1-pm8804-evaluation-board-voltage-converter 2024-06-08 https://elecena.pl/product/26049388/steval-isa203v1-pm8804-evaluation-board-voltage-converter 2024-07-07
