1.4 Device Information

The TPS7H4011 is a 14V, 12A synchronous buck converter optimized for use in a space environment. High efficiency and reduced component count are achieved through peak current mode control. The wide voltage range of the TPS7H4011 enables the device to be used as a point of load regulator to convert directly from a 12V rail. Additionally, various features are included such as differential remote sensing, selectable current limit, a flexible fault input pin, and configurable compensation.

Further information about the TPS7H4011-SP can be found in the TPS7H4011-SP and TPS7H4011-SEP 4.5V to 14V Input 12A Radiation Hardened Synchronous Buck Converter data sheet.
