STMicroelectronics VIPer50-E Handbook
The VIPer50‑E is a high‑voltage SMPS integrating a PWM controller and a 620 V/1.5 A vertical power MOSFET on a single silicon chip. It offers adjustable switching frequency up to 200 kHz, current‑mode control, soft‑start, and automatic burst‑mode operation for low‑power standby.
This handbook contains the device’s electrical and thermal ratings, pin functions, typical application circuits, layout guidelines, and revision history, helping designers implement the part in offline power‑supply designs.
