LM2595 Series Buck Regulator Design Procedure (Fixed Output) (Continued)
LM2595 Series Buck Regulator Design Procedure (Adjustable Output)
PROCEDURE (Adjustable Output Voltage Version)
EXAMPLE (Adjustable Output Voltage Version)
Given:
V
OUT = Regulated Output Voltage
V
IN(max) = Maximum Input Voltage
I
LOAD(max) = Maximum Load Current
F = Switching Frequency
(Fixed at a nominal 150 kHz).
Given:
V
OUT = 20V
V
IN(max) = 28V
I
LOAD(max) = 1A
F = Switching Frequency
(Fixed at a nominal 150 kHz).
1. Programming Output Voltage (Selecting R
1 and R2,as
shown in
Figure 1)
Use the following formula to select the appropriate resistor
values.
Select a value for R
1 between 240Ω and 1.5 kΩ. The lower
resistor values minimize noise pickup in the sensitive feed-
back pin. (For the lowest temperature coefficient and the best
stability with time, use 1% metal film resistors.)
1. Programming Output Voltage (Selecting R
1 and R2,as
shown in
Figure 1)
Select R
1 to be 1 kΩ,1%. Solve for R2.
R
2 = 1k (16.26 − 1) = 15.26k, closest 1% value is 15.4 kΩ.
R
2 = 15.4 kΩ.
