The TPS7H4203 is a 10V to 38V, 3A synchronous buck converter optimized for use in a space environment. The peak current mode converter offers high efficiency, excellent transient performance, and a lower component count.
The TPS7H4203 wide voltage range allows it to function as a point-of-load regulator, converting power directly from 28V or 12V rails. The SS_TR pin controls the output voltage startup ramp, while the EN and PWRGD pins enable power sequencing capabilities.
Two devices can be configured in parallel without an external clock for increased current capabilities. Additionally, the device includes configurable loop compensation and slope compensation. Internal protection for overload, overvoltage, and over temperature are also incorporated.
