High-Voltage 35W DC-DC Converter

Beta Dyne’s new 35W high-voltage dc-dc converter provides isolated output voltages of 48Vdc (±24V) up to 450Vdc (±225V) based on customer need. When its dual output is used, the converter can power any high-voltage power amplifier requiring ±24V to ±225V. When a pair of converters is employed, they can provide ±450V to power OPAMs. The converter has a 2-to-1 input voltage range with nominal voltages of 12Vdc, 24Vdc, 48Vdc and 120Vdc. The customizability afforded by its design means customers can specify their own models and a custom part number will be assigned based on customer specifications.

Features of the new customizable converter include 86% efficiency, input undervoltage and overvoltage protection, input-to-output isolation, soft start, dual short-circuit protection, 500µA off-state current, multiple converter synchronization, adjustable outputs, 100kHz switching frequency, thermal protection, and six-sided shielding. Package size is 2 in. × 2 in. × 0.5 in (50.8 mm × 50.8 mm × 12.7 mm). Ideal applications include telecommunications equipment, micro-mirror devices, DSL systems, remote feed systems, battery power systems, transducer drivers, and high-voltage power OPAMs.
