Operating information
Extended information for POLA products is found in
Application Note 205.
Input Voltage
The input voltage range 4.5 to 14 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 0.1V.
Remote Control (RC) Inhibit
The products are fitted with a
remote control function referenced
to positive logic. The RC function
allows the regulator to be turned
on/off by an external device like a
semiconductor or mechanical
switch. The RC pin has an internal
pull up resistor to + In.
The maximum required sink current is 1 mA. When the RC
pin is left open, the voltage generated on the RC pin is
4.5 – 14 V. The regulator will turn on when the input
voltage is applied with the RC pin open. Turn off is
achieved by connecting the RC pin to the - In. To ensure
safe turn off the voltage difference between RC pin and the
- In pin shall be less than 1V. The regulator will restart
automatically when this connection is opened.
External Capacitors
Input capacitors:
The PMP 5818UW P requires a combination of one 22 F
X5R/X7R ceramic and 330 F electrolytic type. The ripple
current rating of the electrolytic capacitor must be at least
950 mA rms. The ripple current rating must increase to
1500 mA rms when Vo > 2.1V and Io ≥11A.
If using the ceramic capacitor as the input capacitor, the
PMP 5818UW P needs a minimum input capacitance of 300
F. In addition, output capacitor also need ceramic
capacitor, PMP 5818UW P needs a minimum output
capacitance of 300 F.
For high-performance/transient application, or wherever the
input source performance is degraded, 680 F of input
capacitance is recommended. The additional input
capacitance above the minimum level insures an optimized
performance.
Output capacitors:
The PMP 5818UW P requires a minimum output
capacitance of 220 F of aluminium, polymer-aluminum,
tantalum, or polymer-tantalum type.
