Product Details

HV912x Series High-Voltage Current-Mode PWM Controllers

The Microchip HV912x range of high-voltage current-mode PWM controllers are Switch Mode Power Supply (SMPS) controller subsystems that can start and run directly from almost any DC input such as 12V batteries and a rectified and filtered 240VAC line.

These devices can self-start directly from a high voltage input and subsequently take the power to operate from one of the outputs of the converter it is controlling, allowing very efficient operation while maintaining input-to-output galvanic isolation limited in voltage only by the insulation system of the associated magnetic assembly. A ±2% internal bandgap reference, internal operational amplifier, very high speed comparator, and output buffer allow production of rugged, high performance, high efficiency power supplies of 50W or more, which can still be over 80% efficient at outputs of 1.0W or less. Remote on/off controls allow either latching or nonlatching remote shutdown. During shutdown, the power required is under 6.0mW.
