The VIPer12A is a low power off-line SMPS primary switcher with a fixed 60kHZ switching frequency, 9V to 38V wide range VDD voltage, current mode control, auxiliary undervoltage lockout with hysteresis, high voltage start-up current source, overtemperature, overcurrent and overvoltage protection with auto-restart.
The ViPer12ADIP/AS -E is a low‑power off‑line SMPS primary switcher designed for a wide input voltage range (9 V to 38 V) and applications such as battery chargers, standby power supplies, and auxiliary supplies for TVs or monitors. It features a fixed 60 kHz switching frequency, current‑mode control, and integrated protection (over‑temperature, over‑current, over‑voltage with auto‑restart).
The datasheet includes sections on electrical data, maximum ratings, thermal data, detailed electrical characteristics, pin connections and functions, rectangular U‑I output characteristics, and a wide VDD voltage range. It also lists mechanical data, order codes, and revision history, providing designers with all necessary information to integrate the device into their circuits.
