+VIN

Unregulated

DC Input

GND

ON/OFF

OUTPUT

Keep Feedback Wiring

Away From Inductor Flux

Regulated Output

COUT

CIN

4 Feedback

Locate The Programming Resistors Near

The Feedback Pin Using Short Leads

Ground Plane Construction for Best Results

CFF

VOUT×(R1/(R1+ R2))=VREF

VOUT = VREF(1+ R2/R1)

Where VREF=1.23V

R2=R1((VOUT / VREF)-1)

For 4 PIN:
