1.1.2 Flying capacitor (C4)

Use capacitors with a low-ESR (ex. ceramic capacitors) for optimum performance. Design to provide

low impedance for the wiring between CP terminal (4pin), CN terminal (5pin), and the flying capacitor

(C4).

C4=1uF

1.1.3 Hold capacitor (C6)

Use capacitors with a low-ESR (ex. ceramic capacitors) for optimum performance. Design to provide

low impedance for the wiring between the hold capacitor (C6), V- terminal (6pin) and the GND on the

PCB.

Separate the GND pattern connecting to the hold capacitor (C6) from that connecting to the GND

terminal (8pin), thus suppressing the influence of switching noise by removing the common impedance

of the GND wiring.

Design no short-circuits of V- terminal (6pin) and V+ terminal (3pin) on the PCB pattern.
