4707 Dey Road Liverpool, N.Y. 13088 Manufactured using Rad Hard RH1959MILDICE Radiation Tested to TBD Krad(Si) (Method 1019.7 Condition A) 500KHz Constant Switching Frequency:Synchronizable to 1MHz 4.5A Integrated Switch Internal Slope Compensation Input
Voltage Range from 4.3V to 16V Cycle by Cycle Current Limit Output
Voltages Down to 1.21V Contact MSK for MIL-PRF-38534 Qualification Status
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.
