GDemo Board ver. 1.1
<Jumper Settings>
JP3 : Must be connected
JP2 : To be connected if using SW (CE pin fixed to V
* Use tinned copper wire for V
* 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 220µF 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.)
