STMicroelectronics ViPer100-E SMPS Primary IC Datasheet
The ViPer100-E is a Single-Stage Power Supply (SMPS) Primary IC made using VIPower MOS technology. It combines a state-of-the-art PWM circuit with an optimized, high-voltage Vertical Power MOSFET (620V/3A) on the same silicon chip. Typical applications include offline power supplies with a secondary power capability of 50W in wide range conditions and 100W in single range or with doubler configuration.
