FEATURES:

DESCRIPTION:

range with 4.5A 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. The regulator

output can be turned on and off remotely with logic levels via the shutdown pin for meeting power sequencing requirements.

Short circuit current limit and thermal shutdown features provide fault protection. The MSK 5052RH is packaged in a

hermetically sealed 40 pin flatpack with straight or gull wing leads and specifically designed for space/satellite applications.
