Description
The MSK5055RH is a radiation hardened wide input voltage range step-down synchronous switching regulator controller.The wide input range, programmable output voltage and switching frequency, make these regulators suitable for awide variety of medium to high power applications. The adjustable operating frequency provides the flexibility to keep theswitching noise out of sensitive frequency bands, and when synchronized, can be ganged out of phase with other controllersfor reduced noise and component size. The MSK5055RH is hermetically sealed in a 16 pin flatpack, and is available with straight or gull wing leads.
