Part Number: TPS54719 Hi Team,
Normally I found that power good pins are pulled up to output of the switcher, but here it's connected to the Input source. As per mu knowledge Power good is enabled only after the output voltage came 50 or some% My question…
Part Number: TPS54719 Other Parts Discussed in Thread: TPS62867 , Hi, Pls review the attached schematics. Vout = 3.3V, Output Current required = 6A, Vin = 5V
Hi Yokota-san,
Thanks for bringing this to our notice.
You were seeing the issue because the Minimum on time of the device TPS54719 was being violated at 1.9 MHz at 5.5V Vin,0.9V Vout,3.5A Iout condition.
We have made changes to frequency ceiling…
