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

Devices in the AEQ series supply up to 600 VDC at 0.5 W output power from an input voltage of +5 VDC and offer several benefits compared to other small form factor DC-DC converters. These include an output that is proportional to the control pin voltage, giving 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 ±1500 VDC supports precise output voltage control and meets safety levels required for handheld equipment, in addition to supporting compliance in medical and life science applications.

“Due to 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 hand-held and portable devices ranging from silicon detectors and avalanche photo diodes to MEMS devices and ultrasonic transducers. Programmable control enhances flexibility, precision and reliability to address specific application needs.”

The AEQ series comprises unipolar 100 V to 600 V models and bipolar versions from ±50 V to ±300 V, with higher power and voltage levels planned for subsequent releases. Housed in a 0.5- x 0.5- x 0.5-inch (12.7- x 12.7- x-12.7-mm) solid vacuum encapsulated package, the converters are protected against shock and vibration. All devices have UL/cUL and IEC-62368-1 safety approvals.
