LP3382S Datasheet, PDF (8/9 Pages) Lowpower Semiconductor inc – 1.2MHzFixed-Frequency PWM Operation

Layout Consideration
Preliminary Datasheet
For best performance of the LP3382S, the following
guidelines must be strictly followed.
※ Input and Output capacitors should be placed
close to the IC and connected to ground plane to
reduce noise coupling.
※ The GND and Exposed Pad should be connected
to a strong ground plane for heat sinking and
noise protection.
※ Keep the main current traces as possible as short
and wide.
※ LX node of DC-DC converter is with high
frequency voltage swing. It should be kept at a
small area.
※ Place the feedback components as close as
possible to the IC and keep away from the noisy
devices.
