ultra small size adjustable output type high voltage power supply 2w to 2.6w high voltage dc-dc converter 0v-470v ? 1000v ? 1500v ? 2000v vhv series the vhv series is the first high voltage product supply in the industry to use the latest smt (surface mount technology) making the size 1/5 to 1/6 from the normal product, with an adjustable output voltage type mid-high voltage dc-dc converter. output voltage can be controled using an external voltage or external adjustable resistor. the vhv series has adopted a 5 side metallic shield, with farther low ripple and low noise. features ? pcb mounting type ? adopted a 5 sided metallic shield case ? output capacity 2w to 2.6w ? remote on/off control ? over current protection ? high reliability, long life ? worlds smallest size device ? low ripple noise of 30mvp-p ? low price ? adjustable voltage using an external voltage ? ul certified product (ul file no. e305960) model name/rating specifications note1: the output voltage can be controlled by impressing the vcont voltage. using an adjustable resistor or an external voltag e,voltage should be impressed on the vcont pin in order to control the output voltage. when vcont voltage=0v the output voltage(residual output voltage) should be less than 0.5% of the max output volta g e ( at input / output ratin g ) . test circuit block diagram warnin g 1: the input-output g round line and case are internall y connected. warnin g 2: vref is 4v ( when external vr=5k ) warnin g 3: the on/off can be controlled with a transistor. www.volgen.com kaga electronics/volgen dc/dc converters 12v + + sw1 +vin -vin vout (+ or -) vout (com) vcont vref on/off on/off control part load 1 2 7 6 3 4 5 dc-ac switch circuit high voltage oscillating transistor high voltage recitification part control i c voltage detection circuit case external voltage (0 to 4v) or vr (5k ) sw1 open=on short=off output voltage control over current protection standard voltage part bhv20110111
