General Description
Aeroflex’s ACT861X series of power supply modules are radiation hardened 50 Watt units designed for use in space applications. Using a double ended forward topology with synchronous rectifiers achieves high efficiency, and the use of Chip-On-Board (COB) construction together with planar magnetics allows Aeroflex to provide space quality components at down-to-earth prices. The ACT861X series are full featured single output converters, with EMI filtering, short ...
