I burnt one board before this, however I do not understand what is the reason. Please help verify the connections. AVDD = 5V/1A VLD=5V/2.5A Vset= 0.2V Connect EP to 2.7V, EN- J1 jumper set, to bias EN at half of AVDD(2.5V). Differential EP-EN =200mV. Please note as per datasheet, these pins are TTL compatible for CW mode. All that matters is differential between EN and EP to enable device. Set jumpers: J_PD_SEL: 1-2 initially(powers down board). Once connection is made and verified place jumper at 2-3 to enable the device. J_MODE_SEL: 2-3(low current CW mode) J_RBIAS_Control: 1-2(Disabled). No impact if its enabled, its an additional current source. Total current = I(load) + Icc(due to Rbias). On board resistor is 20k, max additional current is 5mA. Initially use LED to validate setup. Measure current through source meter. If it works, use a dummy resistor as load(1ohm). I plan to probe voltage across this resistor using scope. Let me know if any clarification is needed.

These cannot be imported and used in ECAD software and are unhelpful as design files. https://www.ti.com/tool/TIDM-TM4C129XS2E#design-products Is there a way to obtain the schematic file for the product in the above link? I see that a zip file of the layout gerbers seem to be uploaded, but the schematic that corresponds is uploaded as a PDF file for some reason. Thank you!TM4C129XKCZADTIDM-TM4C129XS2Ehttps://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1633032/tmdscncd28379d-connecting-the-control-card-to-a-custom-made-board/6299244Tue, 07 Apr 2026 21:35:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:37d6aa3a-2e4c-4d89-88c1-701582bb44e6Stevan DuraskovicHello, 1. The Control Card uses a diode OR-ing circuit (diodes D1 and D3) to combine USB_5V0 and HSEC_5V0 . When both sources are active simultaneously, the higher-voltage source powers the board while the diode on the lower-voltage path is reverse-biased — preventing any backflow to your PC or your custom supply. So, plugging in USB while your custom 5V is live will not cause a conflict in normal operation. Based on errata in EVM's users guide, you should make sure this is taken care of: Issue Detail Action Required Resistor R83 Populated for standalone evaluation; adds excess capacitance to USB 5V beyond USB spec when used with a baseboard Remove R83 when using the Control Card with your custom board USB ground isolation The micro-USB port (J8) is not isolated from board ground — risk of ground loops in high-power applications Consider external USB isolation buffers if USB is active during high-power operation Please refer to this E2E forum: TMS320F28379D: power supply for the TMS320F28379D controlCARD - C2000 microcontrollers forum - C2000 ™ ︎ microcontrollers - TI E2E support forums Also note: if your custom board's 5V supply is marginal, be aware that insufficient current capacity can cause the rail to sag. A real-world case showed the supply dropping from +5V to +2V when the Control Card was connected — resolved by using a dedicated external 5V supply with adequate current headroom. Please refer to this E2E forum: TMS320F28379D: Configure ControlCard TMS320F28379D - C2000 microcontrollers forum - C2000 ™ ︎ microcontrollers - TI E2E support forums 2. During Power-on Reset and Warm Reset, all I/O pins default to GPIO inputs with pull-ups disabled. T his means the MCU is not actively driving anything, but it also means it is not protecting those pins from being driven externally. Recommended power sequence: 1. Apply 5V to Control Card via HSEC connector (pins 95/97 for +5V, pins 96/98 for GND) 2. Wait for MCU boot ROM to complete (~1ms after reset release) 3. Enable peripheral power supplies 4. Connect USB (if needed for debugging) — USB first is also acceptable per reference designs 3. You have two complementary mechanisms to control execution start: a. Configure Boot Mode Switch SW1 on the Control Card For your use case (controlled start), Wait Boot Mode (00) gives you the ability to hold the MCU idle after power-up and trigger execution externally. For autonomous operation (MCU runs immediately on power), use Flash Boot (Mode 03) b. Hardware reset MCU The most direct hardware control mechanism is the XRS (reset) pin : Hold XRS low → MCU stays in reset, no code executes, all I/O remains in default safe state Release XRS → Boot ROM runs (~1ms), Boot Mode Select Pins (GPIO72 and GPIO84) are sampled, then user code begins Please let me know if you have any questions or concerns.https://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1633545/ucc2897a-please-help-me-to-design-the-tranformer/6299084Tue, 07 Apr 2026 19:41:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:01e36665-3943-438f-aa55-2d1b436a540bAdhvaidh AravindHi Pradeep, I would suggest using TI Power Stage Designer .

We want to power it up using the custom board's 5V supply. But we are not sure how it will effect the Control Card when we plug in the usb to the Control Card board while the custom board's 5V supply is on. We believe there will be conflict. Can you guide us? Also, should the supply to pheripherals connected to the uC be switched off because it may be so that some signal would come to the analog and gpio pins when uC is booting up? What should be the power up sequence? And if we want to make the uC to start executing its code. Like start sensing voltages, perform control action and create some PWM's, etc, how should we start it? We want to have control over when it is on and when it is off.
