●Board Layout
PCB layout considerations:
・Input capacitor CIN connected to VCC (Vin) should be placed as close to VCC(VIN) pin as possible.
Output capacitor COUT also should be placed as close to IC pin as possible. In case the part is connected to inner layer
GND plane, please use several through holes.
・FB pin has comparatively high impedance and can be affected by noise, so stray capacitance should be as small as
possible. Please take care of this during layout.
・Please make GND pattern wide enough to handle thermal dissipation.
・For output voltage setting
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)
