Application Note
1. Application circuit example (top view)
The figure below shows the recommended configuration for TCK106G, TCK107G and TCK108G.
1) Input capacitor
An input capacitor (C
IN
) is not necessary for the guaranteed operation of TCK106G, TCK107G and TCK108G.
However, it is recommended to use input capacitors to reduce voltage drop due to sharp changes in output current
and also for improved stability of the power supply. When used, place C
IN
as close to V
IN
pin to improve stability of
the power supply. Also, due to the C
IN
selected, V
IN
< V
OUT
may occur, causing a reverse current to flow through
the body diode of the pass-through p-ch MOSFET of the load switch IC. In this case, a higher value for C
IN
as
compared to C
L
is recommended.
2) Output capacitor
An output capacitor (C
OUT
) is not necessary for the guaranteed operation of TCK106G, TCK107G and TCK108G.
However, there is a possibility of overshoot or undershoot caused by output load transient response, board layout
and parasitic components of load switch IC. In this case, an output capacitor with C
OUT
more than 0.1F us
recommended.
3) Control pin
A control pins for TCK106G and TCK107G are both Active High and TCK108G is Active Low. These controls
both the pass-through p-ch MOSFET and the discharge n-ch MOSFET (except TCK106G), operated by the
control voltage and Schmitt trigger. When the control voltage level is High (Low; TCK108G), p-ch MOSFET is ON
state and n-ch MOSFET is OFF state. When control voltage level is Low (High; TCK108G), and the state of the
MOSFETs is reversed. Also, pull down resistance equivalent to a few MΩis connected between CONTROL and
GND, thus the load switch IC is in OFF state even when CONTROL pin is OPEN(except TCK108G). In addition,
CONTROL pin has a tolerant function such that it can be used even if the control voltage is higher than the input
voltage.

Power Dissipation
Power dissipation is measured on the board condition shown below.
[The Board Condition]
Board material: Glass epoxy (FR4)
Board dimension: 40mm x 40mm (both sides of board)，t=1.8mm
Metal pattern ratio: a surface approximately 50%, the reverse side approximately 50%
Through hole: diameter 0.5mm x 28
Please allow sufficient margin when designing a board pattern to fit the expected power dissipation. Also take into
consideration the ambient temperature, input voltage, output current etc and applying the appropriate derating for
allowable power dissipation during operation.
