Application Information
6.1
Input and Output Impedance
The POL converter should be connected to the DC
power source via low impedance.
In many
applications, the inductance associated with the
distribution from the power source to the input of the
converter can affect the stability of the converter.
Internally, the converter includes 4.7μF (low ESR
ceramics) of input capacitance which eliminates the
need for external input capacitance. However, if the
distribution of the input voltage to the POL converter
contains high inductance, it is recommended to add
a 100μF decoupling capacitor placed as close as
possible to the converter input pins.
A low-ESR
tantalum or POS capacitor connected across the
input pins help ensuring stability of the POL
converter and reduce input ripple voltage.
A 22μF ceramic output capacitor is recommended to
improve output ripple and dynamic response.
It is important to keep low resistance and low
inductance of PCB traces for connecting load to the
output pins of the converter in order to maintain good
load regulation.

Output Voltage Programming
The output voltage can be programmed from 0.59V
to 5.1V by connecting an external resistor RTRIM
between TRIM pin (Pin 5) and GND pin (Pin 3), as
shown in Figure 12.
