*1. Rating is defined as a total of VR1 and VR2 in the VR bloc.

*3. The power dissipation figure shown is PCB mounted. Please refer to page 41 for details. Also, the power dissipation value above is

for each channel.

* XC9235 control scheme is a fixed PWM because that the “CE/MODE Control Logic” outputs a low level signal to the “PWM/PFM Selector”.

* XC9236 control scheme is an auto PWM/PFM switching because the “CE/MODE Control Logic” outputs a high level signal to the “PWM/PFM Selector”.

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