STMicroelectronics VIPER50A-E Manuals

This document describes the features and characteristics of VIPer50A-E/ASP-E SMPS PRIMARY I.C., including 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, and low stand-by current.

VIPer50A-E/ASP-E is an integrated high-voltage, high-power MOSFET PWM controller featuring adjustable switching frequency, soft start and shutdown control, automatic burst mode operation, internally trimmed zener reference, undervoltage lockout with hysteresis, integrated start-up supply, over-temperature protection, low standby current and adjustable current limitation.

VIPer50A-E/ASP-E is a single-chip switch power supply controller from ST. It uses VIPower M0 technology and integrates high voltage MOSFET and PWM circuit, with adjustable switching frequency, soft start and shutdown control, automatic burst mode operation, low standby current, adjustable current limitation and other features. It is suitable for 25W wide range or single range output power supply or switch power supply with doubler configuration.
