The QLS08ZH 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 μ F electrolytic
capacitor with the ESR<0.7 Ω is recommended for
the QLS08ZH.

how to limit the magnitude of the inrush current.

For output decoupling we recommend using a 10 μ F
tantalum and a 1 μ F ceramic capacitors connected
directly across the output pins of the converter.
Note, that the capacitors do not substitute the
filtering required by the load.

Shutdown Feature Description
The ON/OFF pin in the QLS08ZH converter
functions as a normal soft shutdown. It is referenced
to the –Vin pin (see Figure 7). 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.

Typical Application
Figure 3 shows the recommended connections for
the QLS08ZH converter.
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).
