LAYOUT RECOMMENDATIONS

It is recommended that C1and C2 be located within

1cm of the LX2208. The CMP capacitor and resistor

(C3 and R12) should be located close to the IN and

CMP pins. Also the high impedance summing node

connecting to the TMP pin should be kept relatively

short to prevent the coupling of noise into this node. It

is important that the LX2208 have a good thermal

path to ambient to dissipate heat. The simplest way

to do this is to heatsink the LX2208 bottom pad

directly to the ground plane by placing 4 or more vias

in the ground pad directly under the LX2208 footprint.
