Evaluation demoboard 3.3 Vout demoboard for IPOL single-voltage regulator TDA38740
The EVAL_TDA38740_3.3VOUT enables full configuration of OptiMOS™ IPOL single-voltage synchronous buck regulator TDA38740 IC using the PMBus and/or using pin-strapped resistors. A USB dongle is used to establish communication between the IC and the PC via the 3-pin on-board header.
Infineon's XDP™ Designer GUI is used to interface and program the TDA38740 IC.
