The VIPer12A is a low-power offline SMPS primary switcher. It features a fixed 60kHz switching frequency, wide input voltage range, and multiple protection functions.
The VIPer12ADIP and VIPer12AS are low‑power off‑line SMPS primary switcher ICs designed for battery‑charger adapters, standby supplies for TVs or monitors, and auxiliary supplies for motor control. They integrate a current‑mode PWM controller, a high‑voltage power MOSFET, and a range of protection functions such as over‑temperature, over‑current, and over‑voltage with auto‑restart.
The datasheet provides detailed pin definitions, absolute maximum ratings, thermal data, electrical characteristics, and typical application schematics. It also includes performance graphs for switching frequency versus temperature, current limitation versus temperature, and rectangular output characteristics for battery‑charging applications.
