PRODUCTION DATA SHEET
USING THE LX1664/65 DEVICES
LAYOUT GUIDELINES - THERMAL DESIGN (continued)
All of these traces should be made as wide and thick as
possible, in order to minimize resistance and hence power losses.
It is also recommended that, whenever possible, the ground, input
and output power signals should be on separate planes (PCB
layers). See Figure 15 – bold traces are power traces.
C5 Input Decoupling (VCC) Capacitor
Ensure that this 1µF capacitor is placed as close to the IC as
possible to minimize the effects of noise on the device.
Layout Assistance
Please contact Linfinity’s Applications Engineers for assistance
with any layout or component selection issues. A Gerber file
with layout for the most popular devices is available upon re-
quest.
Evaluation boards are also available upon request. Please
