Description
The MSK5052RH is a radiation hardened adjustable output voltage switching regulator. A wide input and output voltage range with 4.5A output current capability make these regulators suitable for many applications. Excellent efficiency and a reduced output capacitance requirement minimize power dissipation and board space requirements. 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 MSK5052RH is packaged in a hermetically sealed 40 pin flatpack with straight or gull wing leads and specifically designed for space/satellite applications.
