Industry Standard ½ Brick – 36-75V Input, 3.3V / 60A Output
The AEH60F48 / ALH60F48 is part of Astec’s New Ultra High Density ½ Brick family capable of running 60Amps at 3.3V
output. With Efficiencies up to 92% typical at 3.3V - 60Amps, this product provides a 1% to 2% performance increase in
efficiency over the leading 60Amp competitors and up to 10% higher output current. The operating temperature range (-
40°C to 85°C for the ALH; -40°C to 100°C baseplate for AEH) assures maximum application flexibility. New single-
output models feature superior transient response with excellent stability in high capacitance/low ESR load applications.
This family has an effective thermal adapter plate which allows for heat sinking under particularly harsh conditions.
Without the adapter plate (ALH60) provides a very effective low profile which performs extremely well in convection
cooled applications.
