MIL-PRF-38534 CERTIFIED
4707 Dey Road Liverpool, N.Y. 13088
FEATURES:
DESCRIPTION:
range with 3.5A output current capability make these regulators suitable for many applications. Excellent efficiency and a
reduced output capacitance requirement are the results of a constant or synchronizable switching frequency. The switching
frequency can be controlled by an external signal through the SYNC pin or be set to a constant 500KHz. Short circuit
current limit and thermal shutdown features provide fault protection. The MSK 5048RH is hermetically sealed in a space
saving 5 pin power package and specifically designed for space/satellite applications.
POL Applications
Satellite System Power Supply
Microprocessor, FPGA Power Source
High Efficiency Low Voltage Subsystem
Power Supply
