Adjustable Output Voltage Versions

20097125

Select R1 to be approximately 1 kΩ, use a 1% resistor for best stability.

Component Values shown are for VIN = 20V,

VOUT = 10V, ILOAD = 1A.

CIN:

— 470 µF, 35V, Aluminum Electrolytic Nichicon “PM Series”

COUT:

— 220 µF, 35V Aluminum Electrolytic, Nichicon “PM Series”

D1 — 2A, 60V Schottky Rectifier, 21DQ06 (International Rectifier)

L1 — 100 µH, See Inductor Selection Procedure

R1 —1 kΩ,1%

R2 — 7.15k, 1%

CFF — 3.3 nF

Typical Values

CSS — 0.1 µF

CDELAY — 0.1 µF

RPULL UP — 4.7k (use 22k if VOUT is ≥ 45V)

† Resistive divider is required to aviod exceeding maximum rating of 45V/3mA on/into flag pin.

†† Small signal Schottky diode to prevent damage to feedback pin by negative spike when output is shorted (CFF not being able to discharge immediately will

drag feedback pin below ground). Required if VIN > 40V
