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.

Operating information
Extended information for POLA products is found in
Application Note POLA.
Input Voltage
The input voltage range 4.50 to 5.50 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 50mV.
Remote Control (RC) Inhibit
The regulator will turn on when the input voltage is applied
with the INHIBIT pin open. Turn off is achieved by connecting
the INHIBIT pin to the - In. To ensure safe turn off, the voltage
difference between INHIBIT pin and the - In pin shall be less
than 0.6V. The regulator will restart automatically when this
connection is opened.

Rev
A
The products are fitted with a
remote control 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 INHIBIT pin has an
internal pull up resistor to + In.
