VIPer50BSP Datasheet PDF

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 s INTEGRATED START-UP SUPPLY using around 50% less components when s AVALANCHE RUGGED compared with a discrete solution. Burst mode s OVERTEMPERATURE PROTECTION operation is an additional feature of this device, s LOW STAND-BY CURRENT offering the possibility to operate in stand-by s ADJUSTABLE CURRENT LIMITATION mode without extra components.
