Advanced Energy reveals ultra-miniature DC-DC converters

Devices in the AEQ series supply up to 600VDC at 0.5W output power from an input voltage of +5VDC 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 ±1500VDC supports precise output voltage control and meets safety levels required for handheld equipment, in addition to supporting 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 resident 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. Its programmable control enhances flexibility, precision and reliability to address specific application needs.”

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