DGP30 SERIES – SINGLE OUTPUT
DGP30 SERIES APPLICATION NOTES:
External Capacitance Requirements
No external capacitance is required for operation of the DGP30
Series. However, it is recommended that the DGP30 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 0.05 Ohms from DC to
200KHz is required. External output capacitance is not required
for operation, however it is recommended that 1 F to 10 F of
tantalum and 0.001 to 0.1 F ceramic capacitance be selected for
reduced system noise. Additional output capacitance may be
added for increased filtering, but should not exceed 400 F.
Negative Outputs
A negative output voltage may be obtained by connecting the
+OUT to circuit ground and connecting -OUT as the negative
output.
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 arrangement 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. Since the ON/OFF pin is driven by a 9
volt internal source via a 100K
driven by TTL logic. Attempts to drive this circuit with logic
circuits may result in damage to user circuitry.
resistor, the pin should not be
Output TRIM
The TRIM pin may be used to adjust the output ±5% from the
nominal setting. This function allows adjustment for voltage drops
in the system wiring, as well 5.2 volt outputs for ECL applications.
Figure 1 shows the proper connections to use this function. A
trimpot value of 10K
should be used for the 5 volt output.
A trimpot value of 20K
should be used for 12 and 15 volt outputs.
If the TRIM function is not required the pin may be left floating.
