STEVAL-ISA203V1

STEVAL-ISA203V1 is an evaluation board is designed to demonstrate high efficiency DCDC conversion based on PM8804, 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 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. The secondary side employs the SRK1000 adaptive synchronous rectification controller for flyback converters.
