Test Circuit and layout Guidelines

As in any switching regulator, layout is very important. Rapidly switching currents associated with wiring inductance generate voltage

transients which can cause problems. For minimal inductance and ground loops, the length of the leads indicated by heavy lines should be

kept as short as possible. Single-point grounding (as indicated) or ground plane construction should be used for best results. When using

the Adjustable version, physically locate the programming resistors near the regulator, to keep the sensitive feedback wiring short.

Cin-- 100uF, 75V, Aluminum Electrolytic

Cout-- 1000uF, 25V Aluminum Electrolytic

D1-- Schottky, MBR360

L1-- 100uH, Pulse Eng, PE92108

R1-- 2k, 0.1%

R1-- 6.12k, 0.1%

Vout=VREF*(1+R2/R1)

R2=R1*(Vout/VREF-1)

Where VREF=1.23V, R1 between 1k and 5k
