DESCRIPTION:
The MSK 5059RH is a radiation hardened 500KHz switching regulator controller capable of delivering up to 4.5A of
current to the load. A fixed 500KHz switching frequency allows the use of smaller inductors reducing required board space
for a given design. The 4.5A integrated switch leaves only a few application specific components to be selected by the
designer. The MSK 5059RH simplifies design of high efficiency radiation hardened switching regulators that use a minimum
amount of board space. The device is packaged in a hermetically sealed 16 pin flatpack and is available with straight or gull
wing leads.
