Application circuit example (top view) The figure below shows the example of configuration Control GND LOAD VOUT VIN CIN CL RL 1) Input capacitor An input capacitor be sure to use CIN for the stable operation. And it is effective to reduce voltage overshoot or undershoot due to sharp changes in output current and also for improved stability of the power supply. When used, place CIN more than 1.0μF as close to VIN pin to improve stability of the power supply. 2) Output capacitor An output capacitor (COUT) is not necessary for the guaranteed operation. 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 0.1μF is recommended. 3) Control pin The Control pin controls both the pass-through p-ch MOSFET and the discharge n-ch MOSFET (only for TCK2292xG), operated by the control voltage. Each control pin is equipped with Schmitt trigger. Also, pull down resistance equivalent to a few MΩ is connected between Control and GND, thus the load switch IC is in OFF state even when Control pin is OPEN. (except TCK22975G). A control pin for TCK22975G is Active low and does not have a pull down resistor, please use be sure to fix the potential of the Control pin to High or Low. 2. Reverse current blocking This device has a built-in Reverse current blocking (SW OFF state) circuit to block reverse current from VOUT to VIN when output p-ch MOSEFT turned off and input voltage is 0V. 3. Instructions and directions for use This device has built-in several functions, but these do not assure for the suppression of uprising device operation. In use of these products, please read through and understand dissipation idea for absolute maximum ratings from the above mention or our ‘Semiconductor Reliability Handbook’. Then use these products under absolute maximum ratings in any condition. Furthermore, Toshiba recommends inserting failsafe system into the design. © 2017-2021 Toshiba Electronic Devices & Storage Corporation 7 2021-11-18 TCK2292xG, TCK2297xG 4.
