Pin settings
7/48
19
CSNS
Current sense input for the switching section. This pin must be connected
through a resistor to the drain of the synchronous rectifier (RDSon sensing)
to set the current limit threshold.
20
PHASE
Switch node connection and return path for the high side gate driver.
21
HGATE
High-Side Gate Driver Output
22
BOOT
Bootstrap capacitor connection. Input for the supply voltage of the high-side
gate driver.
23
LIN
Linear Regulator Input. Bypass to LGND by a 10
µF ceramic capacitor for
noise rejection enhancement.
24
LOUT
LDO linear regulator output. Bypass with a 20
µF (2x10 µF MLCC) filter
capacitor.
