DESCRIPTION
VIPer31SP combines on the same silicon chip a PWM control dedicated to output current regulation together with an optimised high voltage avalanche rugged vertical power MOSFET (600V/1A). Typical applications cover battery chargers with constant current and constant voltage output characteristics, without any optocoupler between primary and secondary sections. Typical output power capability is 15 W in wide range condition and 30 W in single range or with doubler configuration. Burst mode operation is an additional feature of this device, offering the possibility to operate in no load condition with an input power as low as 1W. This feature insures the compliance towards ”Blue Angel” norm and other similar ones. BLOCK DIAGRAM VCC FB COMP OSC ON/OFF - 2.6 V + UVLO LOGIC + 29 V - OVERTEMP.
