产品概览
The VIPER22ADIP-E from STMicroelectronics is a low-power offline SMPS primary switcher that integrates a dedicated current-mode PWM controller with a high-voltage power MOSFET on a single silicon chip. Packaged in an 8-pin DIP format, it operates from 195VAC to 265VAC with a fixed 60kHz switching frequency and delivers up to 20W output power, making it well-suited for battery charger adapters and standby power supplies.
