产品概述

描述

STEVAL-ISA203V1 evaluation board is designed to demonstrate high efficiency DC-DC conversion with 60 W output (12 V/5 A) from 42 to 56 VDC input (48 V nom.), which is especially suitable for telecom applications.

The power conversion stage is based on a flyback topology managed by the PM8804 controller, which features all the integrated circuitry necessary 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 turn off and a programmable current sense blanking time.

The secondary side employs the SRK1000 adaptive synchronous rectification controller for flyback converters.
