DC/DC Converters Deliver 30A At 50ûC Without Derating

March 1, 2002
Designed for applications requiring high current, low voltage, and fast transient response times, the Apollo series of single-output, quarter-brick dc/dc converters can deliver up to 30A in ambient temperatures to 50ûC without derating. Available

Designed for applications requiring high current, low voltage, and fast transient response times, the Apollo series of single-output, quarter-brick dc/dc converters can deliver up to 30A in ambient temperatures to 50ûC without derating. Available in base-plate and open-frame units with 1.2V, 1.5V, 1.8V, 2.5V and 3.3V outputs, the converters provide a recovery time of 100 µs at a 25-ps load step and a 0.1A/µs rate of change. At an output of 3.3V, efficiency is 90.5%. The open-frame converters have a 0.411'' profile and support 0.6'' card-pitch telecomm requirements, while the base-plate versions are said to be ideal for use in wireless base stations deployed in uncontrolled ambient environments. The Apollo series dc/dc converters use on-board heat-transfer devices that drive thermal energy away from heat-dissipating MOSFET transistors. The new power sources are priced at $59 each/1,000.
