NOTE: The signal from CE/MODE Control Logic to PWM/PFM Selector is being fixed to "L" level inside,

and XC9235 series chooses only PWM control.

The signal from CE/MODE Control Logic to PWM/PFM Selector is being fixed to "H" level inside,

and XC9236 series chooses only PWM/PFM automatic switching control.

Diodes inside the circuit are ESD protection diodes and parasitic diodes.

*Diodes inside the circuit are an ESD protection diode and a parasitic diode.
