Part Number: TPS56221 Hi,
My customer does not use PGOOD pin on TPS56221. On this case, he wants Open(floating) on PGOOD pin. Is it correct? If any issues, please let us know.
Thanks and best regards, M.HATTORI.
Part Number: TPS56221 Dear team,
Customer find that when use TPS56221, they pull down EN to GND first, then float, the IC did not work. Vin is on all the time, and also add a ss capacitor 33nF beside EN.
Thanks.
Best regards,
