STMicroelectronics VIPER™ series device, part number VIPER20ASP-E, is an offline flyback topology converter. This monolithic IC integrates a high-voltage power MOSFET with a PWM controller, enabling power conversion up to 20W. It operates with a switching frequency of up to 200kHz and features integrated current limiting and over-temperature fault protection. The VIPER20ASP-E is designed for isolated power supplies, utilizing a 700V breakdown voltage and requiring a Vcc/Vdd supply range of 8V to 15V, with a typical start-up voltage of 11V. The device is housed in a 10-PowerSO package with an exposed bottom pad for enhanced thermal performance, intended for surface mounting. Applications include consumer electronics, industrial power supplies, and LED drivers.
