The Q Series is a broad line of ultra-miniature, high reliability HV DC/DC converters supplying up to 5,000 V in only 0.125 cubic inches and up to 10,000 V in only 0.614 cubic inches. These component-sized converters are ideal for applications requiring minimal size and weight.

The output is directly proportional to the input voltage and is linear from <0.7 V input to maximum input voltage, allowing for an adjustable output voltage. Output is load dependent. Isolation is ±500 V bias on output return. A control pin option allows full control of the output via a high impedance input, ideal for error-amplifier control in closed-loop systems.

No external components or minimum load are required. The output ripple is extremely low for this package size. Light weight and wide temperature range make these units ideal for portable, battery-powered equipment. Many models feature a center-tap option, which creates both a positive and a negative output from one miniature, low cost unit. An alternate pin pattern is available for users wishing to upgrade without modifying their board design.
