Rad Hard 2.0A Switching Regulator -Image

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