Figure 5. Typical Application of PLD08 Series
The PLD Series converters require external input
and output capacitors for proper operation.
A
minimum of a 100 μF capacitor with an ESR <0.1
Ω
is required at the input and at each of the outputs of
the PLD08 Series. Each output has a minimum
current requirement.
For output decoupling, it is recommended using
small ceramic capacitors connected directly across
the output pins of the converter. These bypass
capacitors are to be applied in addition to the
capacitance described above.
Inhibit Feature
The Inhibit pin of the PLD08 converter, functions as
a normal soft shutdown, referenced to the GND pin
(see Figure 5). When the Inhibit pin is pulled low to
within 0.4 V of ground, the outputs are turned off
and the unit goes into low input power mode.
When the pin is left floating or pulled high to Vin,
the unit is on and operates normally.
