Questions about TPS40057
HDRV and LDRV pin is not pulse.
1.I want to know which parts of the internal circuitry are destroyed, resulting in no pulses from the HDRV and LDRV pins and a DC output.
2.I want the block diagram…
Part Number: TPS40057 Hello E2E, On our board, the TPS40057 output 3.3V and 10A from Vin=28V. When output current change instantly from 10A to 0A, the device has stop. I read the datasheet, I could not to found the content about it.
Could TI explain about…
