The VIPer12A is a low power offline switch mode power supply primary switcher with a fixed 60kHz switching frequency, wide voltage range from 9V to 38V, current mode control, auxiliary undervoltage lockout, etc.
The VIPer12ADIP and VIPer12AS are low‑power offline SMPS primary switchers that integrate a current‑mode PWM controller and a MOSFET on the same silicon chip. They are intended for applications such as battery‑charger adapters, standby supplies for TVs or monitors, and auxiliary supplies for motor control.
The document provides detailed pin descriptions, absolute maximum ratings, thermal data, and electrical characteristics including switching frequency, input voltage range, drain‑source voltage limits, and protection features such as over‑temperature, over‑current and over‑voltage with auto‑restart.
