The TPS7H401x devices are 14V synchronous buck converters optimized for use in a space environment. The TPS7H4012 is a 6A device and the TPS7H4013 is a 3A device. The peak current mode converter obtains high efficiency with good transient performance and reduced component count.
The wide voltage range of the TPS7H401x 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.
Additionally, various features are included such as an optimized current limit for each device, a flexible switching frequency, and configurable compensation.
