Description
General part information
TPS7H4011-SP Series
The TPS7H4011 is a 14V, 12A synchronous buck converter optimized for use in a space environment. The peak current mode converter obtains high efficiency with good transient performance and reduced component count.
The wide voltage range of the TPS7H4011 enables it to be used as a point of load regulator to convert directly from a 12V or 5V rail. The output voltage start-up ramp is controlled by the SS_TR pin. Power sequencing is possible with the EN and PWRGD pins.
The device can be configured with up-to four devices in parallel without an external clock for increased current capabilities. Additionally, various features are included such as differential remote sensing, selectable current limit, a flexible fault input pin, and configurable compensation.
