VIPer100BSP - STMicroelectronics

VIPer100BSP SMPS PRIMARY I.C.

VIPer100B/100BSP, made using VIPower M0 Technology, combines on the same silicon chip a state-of-the-art PWM circuit together with an optimized high voltage avalanche rugged Vertical Power MOSFET (400 V / 6 A). Typical applications cover off line power supplies with a secondary power capability of 100 W in a US mains lines configuration. It is compatible fro.

Features

oth primary or secondary regulation loop despite using around 50% less components when compared with a discrete solution. Burst mode operation is an additional feature of this device, offering the possibility to operate in stand-by mode without extra components.
