Pin
Pin functions (continued)
+5 V low-side gate driver supply. Bypass with a 100 nF capacitor to PGND.
Current sense input for the switching section. This pin must be connected
through a resistor to the drain of the synchronous rectifier (R
set the current limit threshold.
Switch node connection and return path for the high-side gate driver.
High-side gate driver output
Bootstrap capacitor connection. Positive supply input of the high-side gate
driver.
Linear regulator input. Connect to VDDQ in normal configuration or to a
lower supply to reduce the power dissipation. A 10 μF bypass ceramic
capacitor is suggested for noise rejection enhancement. See
Device description on page 20
LDO linear regulator output. Bypass with a 20 μF (2x10 μF MLCC) filter
capacitor.
