This document describes the VIPer20A-E SMPS primary I.C. released in June 2006, which features adjustable switching frequency up to 200 kHz, current mode control, 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 stand-by current, and adjustable current limitation.
The VIPer20A-E is a primary-side regulated SMPS IC utilizing VIPower M0 Technology. It integrates a PWM circuit with a high-voltage vertical power MOSFET (700V/0.5A) on a single chip, designed for offline power supplies with a secondary power capability of up to 20W. Key features include adjustable switching frequency up to 200 kHz, current mode control, soft start/shutdown, automatic burst mode for low standby power, and integrated over-temperature protection.
