DESCRIPTION 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 from both 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. FEATURE ■ ADJUSTABLE SWITCHING FREQUENCY UP TO 200KHZ ■ CURRENT MODE CONTROL ■ SOFT START AND SHUT DOWN CONTROL ■ AUTOMATIC BURST MODE OPERATION IN STAND-BY CONDITION ABLE TO MEET ”BLUE ANGEL” NORM (<1W TOTAL POWER CONSUMPTION) ■ INTERNALLY TRIMMED ZENER REFERENCE ■ UNDERVOLTAGE LOCK-OUT WITH HYSTERESIS ■ INTEGRATED START-UP SUPPLY ■ AVALANCHERUGGED ■ OVERTEMPERATURE PROTECTION ■ LOW STAND-BY CURRENT ■ ADJUSTABLE CURRENT LIMITATION
