5V to 600V dc

Oct 05, 2023

In 12.7mm cubes, Advanced Energy Industries has created a range of regulated dc-dc converters that can take in 5V and output up to 600V, depending on version, each one adjustable from 0V to its maximum value.

Called the AEQ series, all its members are 500mW converters (250mAin max), with different models giving a choice of outputs: 100V (5mA), 200V (2.5mA), 300V (1.67mA), 400V (1.25mA), 500V (1mA), 600V (833μA), ±50V (5mA), ±100V (2.5mA), ±150V (1.67mA), ±200V (1.25mA), ±250V (1mA) or ±300V (833μA).

Output voltage is proportional to between 100mV and 5V applied to the control pin, and is independent of the supply voltage, but load regulation can be as soggy as 30%.

"Output voltage is load-dependent", according to the company. "At light or no-load conditions, the control pin must be compensated to allow the high voltage output to remain in the maximum rated output."

An input capacitor of 10μF or less is suggested, plus an optional RC filter (1 – 10nF plus resistor to suit current) if ripple needs to be below the normal ≤1%.

All devices have UL/cUL and IEC-62368-1 safety approvals and ±1.5kV input-to-out isolation.

MTBF is estimated to be above 1,000,000 hours (MIL-HDBK-217F), and the package to >3,000,000 hours (Bellcore TR332).

Medical, life science, industrial and semiconductor-related applications are foreseen.

Advanced Energy is headquartered in Denver Colorado.
