・Input capacitor C
・FB pin has comparatively high impedance, and is apt to be effected by noise, so floating capacity should be minimum as
・Please take GND pattern space widely, and design layout to be able to increase radiation efficiency.
・For output voltage setting
Designation
Output capacitor C
please use several through hole.
possible. Please be careful in wiring drawing
Output voltage can be set by FB pin voltage(0.800V typ.)and external resistance R1, R2.
(The use of resistors with R1+R2=1k to 90k is recommended)
