QBC DC/DC Series Data Sheet  
132-Watt Quarter-Brick Bus Converter  
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 33µF electrolytic  
capacitor with the ESR<0.7Ω 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 10µF  
low ESR tantalum (AVX TPSC106M025R0500 is  
used in our test setup) and a 1µF ceramic

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.

Figure 2. QBC11ZH Input Characteristics  
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.  
Typical Application  
Figure 3 shows the recommended connections for  
the QBC11ZH converter.  
Note:  
If the ON/OFF pin is not used, it can be left floating (positive logic),  
or connected to the -Vin pin (negative logic).
