XC9301/9302

Series

604

GDemo Board ver. 1.1

External Components

Demo Board Connection Layout

PSW ： XP162A12(SOT-89)

NSW ： XP161A12(SOT-89)

→ suitable for SOT-23, SOT-89, CPH-6

： 22μH (SUMIDA CR54)

→ suitable for CR43∼CR105

： U2FWJ44N (Schottky, Toshiba)

→ suitable for MA720, MA735, U2FWJ44N

： 16V 47μF×2 (Tantalum, Nichicon MCE)

→ suitable for 1005 type∼D2 Package

CIN ： 16V 22μF (Tantalum, Nichicon MCE)

16V 220μF (Electrolytic, PJ type)

R1(around 10Ω)

(tantalum around 10μF)

VIN

GND

JP3 : Must be connected

JP2 : To be connected if using SW (CE pin fixed to VIN)

* Use tinned copper wire for VIN pin, VOUT pin, GND pin, JP2, and JP3.

* Connect test pins for TP1, TP2, TP3, and CE.

Note:

Oscillation may occur as a result of input voltage instability when the

output current is large. At such times, we recommend that in place

of the 220

µF PJ type capacitor, you connect R1 & C1 as shown in

the diagram below.

(In case of demo boards ver. 1.1, cut the pattern wire of R1

connecting point, then connect R1.)
