Hi Hung Ting,
Yes, this is correct. The resistor will register a low at the pin and enable PFM mode. You need to drive the pin high with a GPIO, after startup, to enter forced PWM mode.
The TPS8268105 is a forced PWM module, which supports 1.05Vout…
Hi Gordon,
you are right, there is tantalum capacitor but there is higher value to attenuate voltage spike during hot-plugins.
The small input capacitor is placed directly on the module TPS8268105.
So you have input cap but the value of the tantalum…
