Ultra-miniature and programmable high voltage precision DC-DC converters

Advanced Energy Industries, Inc has introduced a new series of ultra-miniature isolated single and dual-output high-voltage DC-DC converters. The UltraVolt AEQ series optimises power conversion in various life science, medical, industrial and semiconductor equipment applications.

Devices in the series provide up to 600VDC at 0.5W output power from an input voltage of +5VDC and supply several benefits compared to other small form factor DC-DC converters. These comprise an output proportional to the control pin voltage, providing complete programmability from zero to the maximum rated value. Output stability is within 5% at maximum Vout and full load. A high input-to-output isolation rating of +/-1500VDC supports precise output voltage control, meets safety levels required for handheld equipment, and supports compliance in medical and life science applications.

"Because of its small size, ease of voltage control and output voltage accuracy and stability, the AEQ series is ideal for use in high-voltage products where space and weight are critical application requirements," said Conor Duffy, vice president of marketing, medical power products at Advanced Energy. "The series is particularly well-suited for handheld and portable devices ranging from silicon detectors and avalanche photodiodes to MEMS devices and ultrasonic transducers. Its programmable control enhances flexibility, precision and reliability to address specific application needs."

The series incorporates unipolar 100V to 600V models and bipolar versions from +/-50V to +/-300V, with higher power and voltage levels planned for later releases. Housed in a 0.5" x 0.5" x 0.5" (cube) solid vacuum encapsulated package, the converters are shielded against shock and vibration. All devices offer UL/cUL and IEC-62368-1 safety approvals.
