This is the product manual of VIPer22ADIP/VIPer22AS low power off line SMPS primary switcher.
The VIPer22ADIP and VIPer22AS are low‑power off‑line SMPS primary switcher ICs designed for applications such as battery‑charger adapters, standby supplies for TVs or monitors, and auxiliary supplies for motor control. They feature a wide input voltage range, current‑mode PWM control, and built‑in protection functions.
This manual details the device description, pin functions, absolute maximum ratings, thermal data, electrical characteristics, and operating sections such as the supply, oscillator, PWM comparator, and over‑temperature protection. It also includes typical application notes, figures, and ordering information.
