Datel AA Series DC-DC Converters

40 Watt 1" x 1" ultra-wide Vin AA series

DATEL Inc. has announced the introduction of a new 1x1 (AA) series that can deliver up to 40 watts of power. This new line of high power-density DC-DC converters from DATEL is the preferred choice for military, industrial, distributed power architectures, telecommunications, and mobile applications.

Offering industry-unique 4.5-9V, and ultra-wide 9-36V or 18-75V input range, the AA series delivers efficiencies up to 89%. Standard output voltages can be trimmed to customer-specific values. These converters offer Input Under-Voltage Lock-Out (UVLO), and are fully protected against output over-voltage and over-temperature conditions. All models have internal over-current and continuous short circuit protection.

Datel 40 Watt 1

The AA series is offered in the standard (1" x 1" x 0.4") footprint and operates over the extended temperature of -40°C to +123°C. It features a positive or negative On/Off Control function and 2250VDC of isolation. In addition, the AA series can be supplied with encapsulated or SMT options.

Please contact our field application engineers by visiting the Ask an Expert page if your application requires customized input/output voltages, alternate pin-out, alternate packaging, UL/CSA60950 or CE Mark 2004/108/EC Certifications. Other options available from DATEL include models optimized for lower power/cost, such as 10, 15 and 30 Watts versions.
