Layout recommendations
The radiated EMI performance of the product will depend on
the PCB layout and ground layer design. It is also important
to consider the stand-off of the product. If a ground layer is
used, it should be connected to the output of the product and
the equipment ground or chassis.
A ground layer will increase the stray capacitance in the PCB
and improve the high frequency EMC performance.
Output ripple and noise
Output ripple and noise measured according to figure below.
See Design Note 022 for detailed information.
Output ripple and noise test setup
Operating information
Extended information for POLA products is found in
Application Note 205.
Input Voltage
The input voltage range 8 to 14 Vdc makes the product easy
to use in intermediate bus applications when powered by a
non-regulated bus converter or a regulated bus converter.
Turn-off Input Voltage
The products monitor the input voltage and will turn on and
turn off at predetermined levels.
The typical hysteresis between turn on and turn off input
voltage is 0.5V.
Turn on/off voltage can be adjusted by using UVLO
(Undervoltage lockout) function. The UVLO character is
defined by the ON threshold (VTHD) voltage. Below the ON
threshold, the Inhibit control is overridden, and the module
does not produce an output.
The UVLO feature allows for limited adjustment of the ON
threshold voltage. It is made by using a single resistor
between the Inhibit/UVLO pin (pin 21) and ground pins (pin
8,9,12,13). The VTHD value can be adjusted from 8.0V to
11V. Default value of VTHD is 7.2V.
