VIPer20/20A, made using VIPower M0 Technology, is a SMPS primary IC that combines an adjustable switching frequency (up to 200kHz), current mode control, soft start and shutdown control, automatic burst mode operation in standby condition able to meet 'blue angel' norm (<1W total power consumption), internally trimmed zener reference, undervoltage lock-out with hysteresis, integrated start-up supply, avalanche rugged, overtemperature protection, low standby current, and adjustable current limitation.
The VIPer20 family combines a high‑voltage avalanche‑rugged vertical power MOSFET with an integrated PWM controller on a single silicon chip. It is intended for off‑line power supplies up to 20 W, offering features such as adjustable switching frequency, current‑mode control, soft‑start, burst‑mode standby operation, and over‑temperature protection.
The document lists absolute maximum ratings, thermal data, ordering numbers, detailed pin descriptions, and electrical characteristics for both the 620 V (VIPer20/SP/DIP) and 700 V (VIPer20A/ASP/ADIP) versions, including oscillator, error‑amplifier, PWM comparator, and shutdown sections.
| Continuous Drain‑Source Voltage (VIPer20/SP/DIP) | 620 V |
|---|---|
| Continuous Drain‑Source Voltage (VIPer20A/ASP/ADIP) | 700 V |
| Maximum Continuous Current | 2 mA |
| Supply Voltage (VDD) | 15 V |
| Power Dissipation at 25 °C | 57 W |
| Thermal Resistance Junction‑Pin | 20 °C/W |
| Thermal Shutdown Temperature | 140 °C – 190 °C |
At 12 V and 100 kHz the operating supply current is about 13 mA.
Thermal shutdown occurs between 140 °C and 190 °C depending on the device.
Both versions are supplied in a DIP‑8 package.
