Rad Hard 2.0A Switching Regulator

DESCRIPTION:

The MSK 5053RH is a radiation hardened 2MHz adjustable output voltage switching regulator. A wide input and outputvoltage range with a 2.0A output current capability make these regulators suitable for a wide variety of applications. Theadjustable switching frequency allows the end user to select the frequency that maximizes the device performance in thegiven application. The switching frequency can be fixed at a chosen frequency with a single resistor or synchronized via theSYNC pin. The MSK 5053RH simplifies design of high efficiency radiation hardened switching regulators that use a minimumamount of board space. The MSK 5053RH is hermetically sealed in a 40 pin flatpack with straight or Gull wing leadsand is specifically designed for space/satellite applications.
