VIPer20/SP/DIP - VIPer20A/ASP/ADIP is a high-voltage, high-power switch-mode power supply that can be used for 10W wide-range or 20W single-range or double-ended configurations.
The VIPer20 family integrates a high‑voltage avalanche‑rugged MOSFET with a current‑mode PWM controller on a single silicon chip. Two variants are offered: the VIPer20/SP/DIP (620 V) and the VIPer20A/ASP/ADIP (700 V), both supporting up to 200 kHz switching frequency, soft‑start, burst‑mode standby and over‑temperature protection.
The document provides absolute maximum ratings, detailed pin descriptions, electrical and thermal characteristics, as well as typical application waveforms and layout guidelines for designers of offline power supplies up to 20 W.
