APPLICATION TIPS
In the application that does a high-speed switching of NJW4841, because the current flow corresponds to the input
frequency, the substrate (PCB) layout becomes an important.
NJW4841 is driving the High-side/Low-side SW gate with high speed to reduce switching losses. The transient voltage
is generated by parasitic inductance and a high-speed current change of high side and low side SW.
You should attempt the transient voltage decrease by making a current loop area minimize as much as possible.
Therefore, you should make a current flowing line thick and short as much as possible.
You should insert a bypass capacitor between the VDD pin and the GND pin to prevent malfunction by transient
voltage and/or exceed maximum input voltage rating. The recommended bypass capacitor is low ESR and fine high
frequency characteristic (NJRC recommends 0.1F or more).An aluminum electrolytic capacitor is recommended for
smoothing capacitor (NJRC recommends 10F or more). However, you should use large capacitor by sufficient
evaluation (assessment) due to load condition and/or application use environment. (There is a possibility that the supply
voltage rises by inductive kickback when the supply current of the inductive load is large.) The bypass capacitors should
be connected as near as possible to the VDD pin.
