LM2672 Series Buck Regulator

Design Procedure (Fixed Output)

PROCEDURE (Fixed Output Voltage Version)

EXAMPLE (Fixed Output Voltage Version)

To simplify the buck regulator design procedure, National

Semiconductor is making available computer design software to

be used with the SIMPLE SWITCHER line of switching

regulators. LM267X Made Simple version 1.0 is available on

Windows® 3.1, NT, or 95 operating systems.

Given:

V

OUT = Regulated Output Voltage (3.3V, 5V, or 12V)

V

OUT =5V

V

IN(max) = Maximum DC Input Voltage

V

IN(max) = 12V

I

LOAD(max) = Maximum Load Current

I

LOAD(max) = 1A

CIN - 22 µF, 50V Tantalum, Sprague “199D Series”

COUT - 47 µF, 25V Tantalum, Sprague “595D Series”

D1 - 3.3A, 50V Schottky Rectifier, IR 30WQ05F

L1 - 68 µH Sumida #RCR110D-680L

R1 - 1.5 k

Ω,1%

CB - 0.01 µF, 50V Ceramic

For a 5V output, select R2 to be 4.75 k

Ω,1%

where V

REF = 1.21V

Use a 1% resistor for best stability.
