This document introduces the features and characteristics of VIPer22A-E power switch devices, including 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 VIPer22ADIP‑E and VIPer22AS‑E are low‑power off‑line SMPS primary switchers featuring a fixed 60 kHz switching frequency, a wide 9 V‑to‑38 V Vpp input range, and integrated protection functions such as over‑temperature, over‑current, and over‑voltage with auto‑restart. Typical applications include battery‑charger adapters, standby supplies for TVs or monitors, and auxiliary supplies for motor control.
The document details absolute maximum ratings, thermal data, electrical characteristics, pin assignments, and operation modes. It includes tables for switching voltage limits, thermal resistance, start‑up and shutdown thresholds, and provides schematic‑style operation descriptions for current‑mode PWM control and feedback pin operation.
