Notes on design of ICs
5．Please check the latest technical material at the time of mass production,
１．Power on sequence
When resistors for setting of output current (Rext) are used commonly by many ICS, in designing for
mass production, take enough care in evaluating IC operation.
It is recommended that decoupling capacitor between power supply and GND should place as near
IC as possible.
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.
