DGP20 Series Application Notes:
External Capacitance Requirements:
No external capacitance is required for operation of the DGP20
Series. However, for maximum performance, it is recommended that
the DGP20 Series use a capacitor of sufficient ripple current capacity
connected across the input pins if a capacitive input source is farther
than 1” from the converter. To meet the reflected ripple requirements
of the converter, an input impedance of less than 0.09 Ohms from at
220 kHz is required. External output capacitance is not required for
operation, however it is recommended that 1 μF to 10 μF of tantalum

and 0.001 to 0.1 μF ceramic capacitance be selected for reduced
system noise. Additional output capacitance may be added for
increased filtering, but should not exceed 400 μF.
Remote On/Off Operation:
The remote On/Off pin may be left floating if this function is not used.
It is recommended to drive this pin with an open collector/drain or a
relay contact. When the On/Off pin is pulled low with respect to the
-INPUT, the converter is placed in a low power drain state. The input
capacitors are kept fully charged in the OFF mode. For proper
operation, do not drive this input from a logic gate directly. The On/Off
pin should never be pulled more than 0.3 volts below -INPUT or have
a voltage greater than +8 volts applied.
