Layout Guide

PCB layout is very important to achieve stable

operation. Please follow these guidelines and

take below figure for reference (take schematic

in Figure 3 as an example). Place ILIM resistor

(R1 and R2 in Figure 3) close to ILIM1/2 pin,

around

IC

to

achieve

better

thermal

performance.
