APPLICATIONS INFORMATION
Input Decoupling (Cin)
A 4.7 mF capacitor either ceramic or tantalum is
recommended and should be connected as close as possible
to the pins of NCP708 device. Higher values and lower ESR
will improve the overall line transient response.
Output Decoupling (Cout)
The minimum decoupling value is 4.7 mF and can be
augmented to fulfill stringent load transient requirements.
The regulator accepts ceramic chip capacitors MLCC. If a
tantalum capacitor is used, and its ESR is large, the loop
oscillation may result. Larger values improve noise
rejection and PSRR.
Enable Operation
The enable pin EN will turn on or off the regulator. These
limits of threshold are covered in the electrical specification
section of this data sheet. If the enable is not used then the
pin should be connected to V
IN
.
Hints
Please be sure the V
in
and GND lines are sufficiently wide.
If their impedance is high, noise pickup or unstable
operation may result.
Set external components, especially the output capacitor,
as close as possible to the circuit.
The sense pin SNS trace is recommended to be kept as far
from noisy power traces as possible and as close to load as
possible.
Thermal
As power across the NCP708 increases, it might become
necessary to provide some thermal relief. The maximum
power dissipation supported by the device is dependent
upon board design and layout. Mounting pad configuration
on the PCB, the board material, and also the ambient
temperature affect the rate of temperature rise for the part.
This is stating that when the NCP708 has good thermal
conductivity through the PCB, the junction temperature will
be relatively low with high power dissipation.
The power dissipation across the device can be roughly
represented by the equation:
P
D
+
ǒ
V
IN
* V
OUT
Ǔ
*I
OUT
[W]
(eq. 1)
The maximum power dissipation depends on the thermal
resistance of the case and circuit board, the temperature
differential between the junction and ambient, PCB
orientation and the rate of air flow.
The maximum allowable power dissipation can be
calculated using the following equation:
P

[W]
(eq. 2)
Where (T
J
− T
A
) is the temperature differential between
the junction and the surrounding environment and q
JA
is the
thermal resistance from the junction to the ambient.
Connecting the exposed pad and non connected pin 3 to
a large ground pad or plane helps to conduct away heat and
improves thermal relief.
