SS is used to adjust the soft-start time. Connect a capacitor from SS to SGND to adjust the soft-
start time (current sharing). C
internal 5µA current source sets the soft-start interval of the converter, t
Input supply voltage for the logic. VDD to be at the same potential as VIN +0.3/-0.5V.
Negative supply for the power stage of Channel 1.
Switching node connection for Channel 1. Connect to one terminal of inductor for VOUT1.
Input supply voltage. Connect 22µF ceramic capacitor to power ground per channel.
The exposed pad must be connected to the SGND pin for proper electrical performance. Add as much
vias as possible for optimal thermal performance.
