TCK104G,tck105g 2014-03-01 6 application note 1. application circuit example (top view) the figure below shows the recommended c onfiguration for TCK104G and tck105g 1) input capacitor an input capacitor(c in ) is not necessary for the gu aranteed operation of TCK104G and tck105g. 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 powe r 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 mo sfet 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 oper ation of TCK104G and tck105g. 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 0.1 f us recommended. 3) control pin a control pins for TCK104G and tck 105g are both active high, which c ontrols both the pass-through p-ch mosfet and the discharge n-ch mosfet, operated by the control voltage and schmitt trigger. when the control voltage level is high, p-ch mosfet is on state and n- ch mosfet is off state. w hen control voltage level is low, 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 lo ad switch ic is in off state even when control pin is open. in addition, control pin has a tolerant f unction such that it can be used even if the control voltage is higher than the input voltage. control voltage ic operation high on low off open off v out gnd v in control c l r l load c in
