SLVK226 October 2025 TPS7H4012-SEP
The TPS7H401x-SEP is a 14V 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 TPS7H4012-SEP supports up to 6A output current while the TPS7H4013-SEP supports up to 3A output current.
The wide voltage range of the TPS7H401x-SEP enables the device 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.
The device is offered in a 44-pin plastic package. General device information and test conditions are listed in Table 1-1. For more detailed technical specifications, user guides, and application notes, see TPS7H4012-SEP product page and TPS7H4013-SEP product page.
