VIPer50-E is a high voltage, high current power switch device, made using VIPower M0 Technology, which integrates a state-of-the-art PWM circuit with an optimized high voltage Vertical Power MOSFET (620V/1.5A). It has adjustable switching frequency, soft start and shutdown control, automatic burst mode operation, internally trimmed Zener reference, undervoltage lock-out with hysteresis, integrated start-up supply, over-temperature protection, low standby current and adjustable current limitation.
This document describes the VIPer50‑E SMPS integrated circuit, including its general features such as adjustable switching frequency up to 200 kHz, current‑mode control, soft‑start, and burst‑mode operation for low‑power standby. It also contains detailed electrical specifications, thermal characteristics, and pin functions for designers.
The manual includes typical application circuits, layout recommendations, mechanical package data, and a revision history. All specifications are presented with test conditions and limits to aid in proper implementation of the device in offline power‑supply designs.
