OUT1
2V Reference Voltage Output. Bypass REF to GND with a 2.2nF ceramic capacitor. The reference can
source up to 100µA. Loading REF degrades output-voltage accuracy according to the REF load
regulation error (see theTypical Operating Characteristics). The reference shuts down when both EN1
and EN2 are low.
This four-level input determines the CSH1 to CSL1 current limit for SMPS1:
In combined mode, ILIM1 sets the current-limit threshold for both sides.
This four-level input determines the CSH2 to CSL2 current limit for SMPS2:
In combined mode, ILIM2 is the current balance integrator (CCI) output pin. Connect a capacitor
