GH2801R8S Datasheet | Micross

Description The GH-Series is a family of low voltage single output DC-DC converters. They are specifically designed in response to the need for low voltage at moderate current levels with the high efficiency and tight regulation dictated by modern digital processing applications. The converters are radiation hardened, high reliability converters designed for extended operation in hostile environments. Their small size and low weight make them ideal for applications such as geostationary earth orbit satellites and deep space probes. They exhibit a high tolerance to total ionizing dose, single event effects and environmental stresses such as temperature extremes, mechanical shock, and vibration. All ponents are fully de-rated to meet the requirements of MIL-STD-975, MILSTD-1547 except for the CDR type of capacitors, a capacitor with 50V rating is used for in-circuit voltage stress of less than10V. Thorough analyses and documentation including beginning-of-life (BOL) and endof-life (EOL) electrical worst case (WCA) operation, ponent stress and de-rating, radiation susceptibility (TREE), thermal stress, failure mode and effects (FMEA), and reliability (MTBF) are available for customer review. The design incorporates a fixed frequency topology with magnetic feedback. Synchronous rectification is deployed to maximize efficiency performance. The converters include an internal EMI filter that is capable of meeting the conducted emission requirements of most major satellite power busses. Incorporation of many functional features including on/off mand, remote sensing, and under-voltage lockout make the design suitable for today’s space design applications. The converter is enclosed in a hermetically sealed package with the overall dimensions of 3.5"L x 2.50”W x 0.475"H including the I/O pins and mounting tabs. The package base material is Aluminum-Silicon-Carbide (AISi C). The package ring frame is Alloy 48. The package utilizes rugged ceramic feed-through copper core I/O...
