Overview
HV9906DB2 Off-Line Current Source Controller Introduction The Supertex HV9906DB2 demo board contains all circuitry necessary to demonstrate the features of the HV9906 second order power supply controller.
The power converter of the demo board consists of an input buck-boost stage and an output buck stage.
The output voltage polarity is negative.
Due to its unique quadratic input-to-output DC voltage transfer ratio, the converter can operate directly off AC line to produce low-voltage output without need for electrolytic capacitors.
HV9906 is designed for optimal controlling this type of power converter or other types of two-stage multi-converters.
The board is optimized for driving a 6V 400mA (700mA max.
) LED.
However, it may be modified to meet custom requirements.
Specification Input Voltage Output Current Output Voltage Efficiency 80 to 135VAC, 60Hz 400mA ±10% (700mA max.
) 10V max.
62% at Io=500mA, Vin=100VAC Board Layout and Connections WARNING!!! Do not connect to scope ground...
