Notes on design of ICs
TC62D722CFG/CFNG
1. Regarding decoupling capacitor between power supply and GND
It is recommended that decoupling capacitor between power supply and GND should place as near IC as possible.
2. Regarding resistors for setting of output current
When resistors for setting of output current (R_EXT) are used commonly by many ICs, in designing for mass production, take enough
care in evaluating IC operation.
3. Regarding PCB layout
There is only one GND terminal on this device when the inductance in the GND line and the resistor are large, the device may
malfunction due to the GND noise when output switching by the circuit board pattern and wiring.
Therefore, take care when designing the circuit board pattern layout and the wiring from the controller.
4. Please check the latest technical material at the time of mass production.
