MSK5044RH

Manufacturer Part Number
MSK5044RH
Description
Rad Hard 3.5a Switching Regulator
Manufacturer
M. S Kennedy
Datasheet
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 500KHz switching frequency. The regulator output
can be turned on and off remotely with low current logic levels via the shutdown pin for meeting power sequencing
requirements. Short circuit current limit and thermal shutdown features provide fault protection. The MSK 5044RH is
hermetically sealed in a space saving 5 pin power package and specifically designed for space/satellite applications.
