Test set-up
Layout recommendation
The radiated EMI performance of the DC/DC regulator will
depend on the PCB layout and ground layer design.
It is also important to consider the stand-off of the DC/DC
regulator.
If a ground layer is used, it should be connected to the output
of the DC/DC regulator 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 AN206.
Input Voltage
The input voltage range 2.95 to 3.65 Vdc makes the product
easy to use in intermediate bus applications when powered
by a regulated bus converter.
Turn-off Input Voltage
The DC/DC regulators monitor the input voltage and will turn
on and turn off at predetermined levels.
The minimum hysteresis between turn on and turn off input
voltage is 0.05V.
Remote Control {Inhibit}
The products are fitted with a
remote control (Inhibit) function
referenced to the primary negative
input connection (- In), positive
logic. The INHIBIT function allows
the regulator to be turned on/off by
an external device like a
semiconductor or mechanical
switch.
The regulator will turn on when the input voltage is applied
with the INH pin open. Turn off is achieved by connecting the
INH pin to the - In. To ensure safe turn off the voltage
difference between INH pin and the - In pin shall be less than
0.6V. The regulator will restart automatically when this
connection is opened.
