CONTROLLER

DESCRIPTION:

The MSK5032 is a 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 MSK5032 simpli-

fies design of high efficiency 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.
