VIPer50/50A is a SMPS PRIMARY I.C. made using VIPower M0 Technology, which features adjustable switching frequency, current mode control, soft start and shut down control, automatic burst mode operation, internally trimmed zener reference, undervoltage lock-out with hysteresis, integrated start-up supply, low stand-by current, and adjustable current limitation.
The VIPer50/SP and VIPer50A/ASP are high‑voltage, avalanche‑rugged power MOSFET modules built with ViPower™ technology. They integrate a PWM controller and a vertical power MOSFET (620 V/15 A for VIPer50/SP, 700 V/1.5 A for VIPer50A/ASP) on a single silicon chip, targeting off‑line power supplies up to 50 W.
Key features include adjustable switching frequency up to 200 kHz, current‑mode control, soft‑start, automatic burst‑mode standby (<1 W), undervoltage lock‑out, over‑temperature protection, and an internally trimmed Zener reference. The document lists absolute maximum ratings, thermal data, pin functions, and detailed electrical parameters.
