ESD Protection
Do not lay out high-voltage traces near the ADJ pin because if the board is contaminated, leakage current
can affect the ADJ pin voltage and cause unintended output current. To further reduce this risk, use a
ground ring around the ADJ pin. (Also see section 2.7 regarding the ZLED7x20’s protection circuitry for
preventing excessive output current.)
To minimize ground bounce, locate the 0.1µF external capacitor C2 as close as possible to the V
solder the ZLED7x20’s GND pin directly to the ground plane. (Also, see section 3.3.4 regarding ground
bounce.)
Because Rs is typically a low value resistor, it is important to consider the resistance of the traces in series
with R
minimize this effect.
The ZLED7x20’s thermal pad must be grounded.
