Figure 2. QBC11ZH Input Characteristics
Typical Application
Figure 3 shows the recommended connections for
the QBC11ZH converter.
Figure 3. Typical Application of QBC11ZH
The QBC11ZH converter does not require any
external components for proper operation. However,
if the distribution of the input voltage to the converter
contains significant inductance, the capacitor C1
may be required to enhance performance of the
converter.
A minimum of a 33
F electrolytic
capacitor with the ESR<0.7
is recommended for
the QBC11ZH.
Refer to the “Inrush Current Control Application
Note” on www.power-one.com for suggestions on
how to limit the magnitude of the inrush current.
For output decoupling we recommend to use a 10
F
low ESR tantalum (AVX TPSC106M025R0500 is
used in our test setup) and a 1
F ceramic
capacitors.
Note, that the capacitors do not
substitute the filtering required by the load.
Shutdown Feature Description
The
ON/OFF
pin
in
the
QBC11ZH
converter
functions as a normal soft shutdown. It is referenced
to the –Vin pin (see Figure 3).
With the positive
logic, when the ON/OFF pin is pulled low, the output
is turned off and the unit goes into a very low input
power mode.
With negative logic, when the ON/OFF pin is pulled
low, the unit is turned on.
An open collector switch is recommended to control
the voltage between the ON/OFF pin and the -Vin
pin of the converter. The ON/OFF pin is pulled up
internally, so no external voltage source is required.
The user should avoid connecting a resistor between
the ON/OFF pin and the +Vin pin.
When the ON/OFF pin is used to achieve remote
control, the user must take care to insure that the pin
reference for the control is really the -Vin pin. The
control signal must not be referenced ahead of EMI
filtering, or remotely from the unit. Optically coupling
the information and locating the optical coupler
directly at the module will solve any of these
problems.
Note:
If the ON/OFF pin is not used, it can be left floating (positive logic),
or connected to the -Vin pin (negative logic).
