VIPer20B/SP is a high voltage switch power supply control chip, which integrates high voltage switching tube, regulator, current limiter and temperature protection, etc. It has adjustable switching frequency, current mode control, soft start and shutdown control, automatic burst mode, low standby power consumption and other features.
The VIPer20B and VIPer20BSP are integrated power MOSFET solutions that combine a high‑voltage MOSFET (400 V, 1.3 A) with a current‑mode control circuit. Features include adjustable switching frequency (0‑200 kHz), burst‑mode operation, low standby current, and built‑in over‑temperature protection.
The document lists absolute maximum ratings, detailed electrical specifications for the power, supply, oscillator, error‑amplifier and PWM comparator sections, as well as ordering numbers, pin descriptions, and mechanical dimensions for the PowerSO‑10 package.
