APW8707B

Layout Consideration

For all switching power supplies, the layout is an impor-

tant step in the design; especially at high peak currents

and switching frequencies. If the layout is not carefully

done, the regulator might show noise problems and duty

cycle jitter.

1. The input capacitors should be placed close to the VIN

pin, and the ground terminals of input capacitors and

output capacitors should be close PGND pin.

2. To minimize copper trace connections that can inject

noise into the system, the inductor should be placed as

close as possible to the LX pin to minimize the noise

coupling into other circuits.

3. The traces of PWM signal from the PWM controller to

the PWM pin of APW8707B should be short to eliminate

the parasitical capacitance; the parasitical capacitance

will cause an invalid PWM signal.
