Application circuit example (top view) The figure below shows the recommended configuration for TCK106AF, TCK107AF and TCK108AF. CONTROL NC Part number GND LOAD VIN CIN VOUT CL RL TCK106AF TCK107AF TCK108AF Control voltage IC Operation HIGH ON LOW OFF OPEN OFF HIGH OFF LOW ON 1) Input capacitor An input capacitor (CIN) is not necessary for the guaranteed operation of TCK106AF, TCK107AF and TCK108AF. 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 CIN as close to VIN pin to improve stability of the power supply. Also, due to the CIN selected, VIN < VOUT 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 CIN as compared to CL is recommended. 2) Output capacitor An output capacitor (COUT) is not necessary for the guaranteed operation of TCK106AF, TCK107AF and TCK108AF. 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 COUT more than 0.1F is recommended. 3) Control pin A control pins for TCK106AF and TCK107AF are both Active High and TCK108AF is Active Low. These controls both the pass-through p-ch MOSFET and the discharge n-ch MOSFET (except TCK106AF), operated by the control voltage and Schmitt trigger. When the control voltage level is High (Low; TCK108AF), p-ch MOSFET is ON state and n-ch MOSFET is OFF state. When control voltage level is Low (High; TCK108AF), and the state of the MOSFETs is reversed. Also, pull down resistance equivalent to a few M is connected between CONTROL and GND, thus the load switch IC is in OFF state even when CONTROL pin is OPEN(except TCK108AF). 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. 5 2015-12-29 TCK106AF/TCK107AF/TCK108AF 2.
