<Instruction on Pattern Layout>
1. In order to stabilize V
IN
's voltage level, we recommend that an input by-pass capacitor (C
IN
) be connected as close as
possible to the V
IN
& V
SS
pins.
2. Please mount each external component as close to the IC as possible.
3. Wire external components as close to the IC as possible and use thick, short connecting traces to reduce the circuit
impedance.
4. Make sure that the PCB GND traces are as thick as possible, as variations in ground potential caused by high ground
currents at the time of switching may result in instability of the IC.
