BLOCK DIAGRAM

* The XCL213 offers a fixed PWM control, a Control Logic of PWM/PFM Selector is fixed at “PWM” internally.

The XCL214 control scheme is a fixed PWM/PFM automatic switching, a Control Logic of PWM/PFM Selector is fixed at “PWM/PFM automatic

switching” internally.

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