VIPer50BSP Datasheet SMPS PRIMARY I.C.

Manufacturer: STMicroelectronics

General Description

s SOFT START AND SHUT DOWN CONTROL VIPer50B made using VIPower M0 Technology s AUTOMATIC BURST MODE OPERATION IN combines on the same silicon chip a STAND-BY CONDITION ABLE TO MEET state-of-the-art PWM circuit together with an ”BLUE ANGEL” NORM (<1W TOTAL POWER optimized high voltage avalanche rugged Vertical CONSUMPTION) Power MOSFET (400 V / 3 A).

Typical s INTERNALLY TRIMMED ZENER applications cover off line power supplies with a REFERENCE secondary power capability of 50W in a US mains s UNDERVOLTAGE LOCK-OUT WITH lines configuration.

It is compatible from both HYSTERESIS primary or secondary regulation loop despite www.DataSheet4U.com s INTEGRATED START-UP SUPPLY using around 50% less components when s AVALANCHE RUGGED compared with a discrete solution.
