TPS7H4011-SP (TPS7H4011EVM-CVAL) Evaluation Module
This user's guide describes the characteristics, operation, and use of the TPS7H4011EVM-CVAL board. This
evaluation module (EVM) is optimized for 4.5V to 14V input voltage range and 12A maximum output current. The
feedback divider and compensation network can be modified for other application conditions according to the
TPS7H4011-SP data
sheet.

The wide voltage range of the TPS7H4011-SP enables it 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. -

333mΩ load resistance created by 3, 1Ω chip resistors connected in parallel. While the CSD16408Q5 power MOSFET is capable of conducting the full 12A output current of the TPS7H4011-SP, the chip resistors are each rated for only 2W. When utilizing the transient circuit on the TPS7H4011EVM-CVAL, the signal sent to the MOSFET gate through TP30 (TRANS) can be modulated to keep the average power through the load resistors below the 2W rating. - Page 6 VOUTremote+ TP30 TRANS TP31 Vremote- VOUT Compact probe tip connector TRANS ILIM_19A RSC_SEL FSW_SEL ILIM_14A Jumper for mode selection SYNCM ILIM_9A SYNC2 ILIM6A TPS7H4011-SP (TPS7H4011EVM-CVAL) Evaluation Module SLVUCK1 – APRIL 2024 Submit Document Feedback Copyright © 2024 Texas Instruments Incorporated...
