Astec Introduces AEH80 and ALH80 DC/DC Converters

Astec Power (Carlsbad, CA) announced its new 80A, half-brick, dc/dc converters. The new family is available in two models: an open-face version, the ALH80, or with a heatsink adapter plate attached, the AEH80. Both models have operating efficiencies of 87 percent while delivering 80A, and 88.5 percent at 60A, at an ambient temperature of 25 degrees C.

The members of the AEH80 and ALH80 families feature ±10 percent output-voltage trim adjustment capability; a positive or negative logic-enable input-control pin; under-voltage lockout with hysteresis, to prevent false starting and stopping at low input voltages; and over-temperature, over-current and over-voltage protection.

With a 36V to 75V input range and output voltages of 1.2V, 1.5V and 1.8V, the new converters are suitable for data and telecommunications applications, including wireless transmitters, receivers and base stations. The converters also feature a wide operating temperature range of –40 to +85 degrees C, and the industry-standard, half-brick, pin-out, footprint and package size of 2.3in x 2.4in.

Priced from $130 in 1,000-piece quantities, samples of the 1.8V model will be available in January 2002.
