APPLICATION INFORMATION
Output Voltage Selection
The output voltage is programmed through an external
resistor divider connect from VOUT to FB then to GND.
For internal compensation and noise immunity, the
resistor from FB to GND should be in 10 k to 20 k ranges.
The relationship between the output voltage and feedback
resistor is given by:
VOUT + VFB
1 )
R1
R2
(eq. 1)
VOUT: Output voltage
VFB: Feedback Voltage
R1: Feedback resistor from VOUT to FB.
R2: Feedback resistor from FB to GND.
Input Capacitor Selection
In the PWM buck converter, the input current is pulsating
current with switching noise. Therefore, a bypass input
capacitor must choose for reduce the peak current drawn
from the power supply. For NCP1596, low ESR ceramic
capacitor of 10
mF should be used for most of cases. Also,
the input capacitor should be placed as close as possible to
the VCCA pin for effective bypass the supply noise.
Inductor Selection
The inductor parameters are including three items, which
are DC resistance, inductor value and saturation current.
Inductor DC resistance will effect the convector overall
efficiency, low DC resistor value can provide a higher
efficiency. Thus, inductor value are depend on the inductor
ripple current, input voltage, output voltage, output current
and operation frequency, the inductor value is given by:
DIL +
VOUT
L
FSW
1 *
VOUT
VIN
(eq. 2)
DIL : peak to peak inductor ripple current
L: inductor value
FSW: switching frequency
After selected a suitable value of the inductor, it should be
check out the inductor saturation current. The saturation
current of the inductor should be higher than the maximum
load plus the ripple current.
DIL(MAX) + DIOUT(MAX) )
DIL
2
(eq. 3)
DIL(MAX)
: Maximum inductor current
DIOUT(MAX)
: Maximum output current
Output Capacitor Selection
Output capacitor value is based on the target output ripple
voltage. For NCP1596, the output capacitor is required a
ceramic capacitors with low ESR value. Assume buck
converter duty cycle is 50%. The output ripple voltage in
PWM mode is given by:
DVOUT [ DIL

) ESR (eq. 4)
In general, value of ceramic capacitor using 20
mF should
be a good choice.
