STMicroelectronics VIPer20/SP/DIP VIPer20A/ASP/ADIP Manual
The VIPer20 family combines a high‑voltage avalanche‑rugged vertical power MOSFET with an integrated PWM controller on a single silicon chip. It is intended for off‑line power supplies up to 20 W, offering features such as adjustable switching frequency, current‑mode control, soft‑start, burst‑mode standby operation, and over‑temperature protection.
The document lists absolute maximum ratings, thermal data, ordering numbers, detailed pin descriptions, and electrical characteristics for both the 620 V (VIPer20/SP/DIP) and 700 V (VIPer20A/ASP/ADIP) versions, including oscillator, error‑amplifier, PWM comparator, and shutdown sections.
