PCB Layout Example & Recommended Land Pattern
(1)Each ground of all components is connected as close as possible to the Pin No.1 at one point.
(2) To help heat dissipation, connect a large copper plane to exposed pad on the back side of the package.
The copper plane is required for GND
Front Side: Component Side (double sided board)
NOTES:
Real size of the PCB is 60mm×60mm
(Demo-board circuit-diagram)
Back Side: GND Side (double sided board)
NR111E
NR119E
As for the part number of the demonstration board "circuit-diagram", a circuit board concerned doesn't partly fit each
other with the above application circuit example and so on for NR110, NR120 and the NR880 series common use.
Approve it in advance. C9, R9 and C10 aren't used in the NR110 series. And, D2, R3, R8,R10, C11 and C12 are options.
*Mount I_SET setup resistor R9 on the position of C10.
