Description
Equivalent Circuit
5
FB
Feedback pin
Sets the output voltage by means of split resistor
in the section of the output voltage VOUT - FB -
GND. VOUT setting is made as calculated
below :
VOUT = Vref × {1+
(R1 + R10)
R3
}
Vref = 0.8V
Example : 3.3V output voltage
(See block diagram and sample application
circuit)
VOUT = 0.8 × {1+
(27k + 4.3k)
10k
}
= 3.304V

Soft start pin
Set the soft start time by means of the built-in 5
μA
source voltage and external soft start capacity
Css can be set as follows :
C6 = 5
μA ×

Vref
Where, Tss is soft start time and Vref is the
reference voltage.
Example : 2.4ms soft start time achieved
Css = 5
