●Ordering Information

XC9103①②③④⑤⑥: PWM Control

XC9104①②③④⑤⑥: PWM/PFM Automatic Switching Control

XC9105①②③④⑤⑥: PWM/PFM Manual Switching Control

The dissipation pad for the USP-6B

package should be solder-plated in

recommended mount pattern and metal

masking so as to enhance mounting

strength and heat release.

If the pad needs to be connected to other

pins, it should be connected to the VDD

(No.2) pin.
