The A Series is a new line of ultra-miniature, DC to HV DC converters that
set an industry standard in high voltage miniaturization. This unique pack-
age occupies less than one tenth of a cubic inch of volume*5, and features
an extremely low profile of only 0.250 inches (6.35mm)! Controllable out-
put voltages range from 100 volts to 6000 volts. These component-sized
converters are ideal for applications requiring minimal size and weight.
Turn-on voltage is very low at less than 0.7 volts, allowing for wide output
voltage operating range. Use of a resonant, quasi-sinewave oscillator and
fully shielded transformer result in clean, reliable high voltage conversion
with inherently low ripple, EMI/RFI and input ripple current, making this
product ideal for integration into noise sensitive equipment.
A separate high impedance control pin is standard and is designed for
external error amplifier and/or DAC control in closed or open loop systems.
Or simply connect the control pin to the + input for proportional input to
output operation (see schematic and performance charts below).
Output power is 1 watt standard, with 1.5 watts available as an option. No
minimum load is required.
A proprietary vacuum encapsulation process and
custom 94V-0 listed, high performance formula are used to achieve excellent
high voltage and thermal properties.
Isolation is +/- 500V bias on the output
return. Input to output leakage current is very low at less than 100 nA and
coupling capacitance is also low at <250 pF.
The new A Series leverages XP EMCO’s Best-in-Class long term reli-
ability, utilizing proven DC to high voltage DC conversion technology,
perfected by over four decades of high voltage design experience in the
most demanding applications. Our extensive in-house capabilities enable
us to meet specific customer requirements with standard, modified and
custom solutions quickly, easily, and economically. Technical assistance is
