ADH700 Series
Active
700 W 1/2 Brick
The ADH700 series half-brick isolated DC-DC converter provides a single regulated 28 V/25 A or 50 V/14 A low-noise 700 W output with >95% efficiency at half load. With an input range of 36 to 75 VDC, the series is designed primarily for standard 48 V telecom equipment, such as remote radio head (RRH) applications. A fixed 280 kHz switching frequency minimizes external EMI filtering requirements. An open-frame design with an aluminum thermal baseplate is optimized for conduction or forced air cooling. You can operate the ADH700 converters over -40 to +85ËšC ambient and with full power delivery up to a baseplate temperature of 100ËšC. Helping you meet demanding inter-board spacing requirements, the converters feature an installed height of just 0.5 inch (12.7 mm).
