Power Management IC Development Tools 48 V flyback converter 12 V - 5 A based on PM8804

Description of product

STMicroelectronics STEVAL-ISA203V1 Evaluation Board is designed to demonstrate high-efficiency DC-DC conversion with 60W output (12V/5A), from 42 to 56VDC input (48V nom.). The STEVAL-ISA203V1 Board offers parameters which are especially suitable for telecom applications.The PM8804 controller features all the integrated circuitry necessary for a compact and efficient 48V converter. The PM8804 manages the flyback topology that the power conversion is based on. 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.
