FUNCTION
Power Ground for WLED Boost Converter. Connect PGND1, PGND2, and AGND to the PCB
ground plane.
Inductor Connection and Switching Node for WLED Boost Converter
WLED Step-Up Converter Output. Connect a 1 F F capacitor from OUT2 to PGND2.
Step-Up Converter Output. Connect a 2.2 F F capacitor from OUT1 to ground.
Inductor Connection and Switching Node for OUT1 Step-Up Converter
Power Ground for OUT1 Step-Up Converter. Connect PGND1, PGND2, and AGND to the PCB
ground plane.
Step-Up Compensation Node for OUT2 Step-Up Converter. Connect a 0.22 F F ceramic capacitor
from COMP to ground. The applied COMP capacitance stabilizes the converter and sets the soft-
start time. COMP discharges to ground through a 20k I resistance when in shutdown.
25mA LED Current Regulator. Connect LED1 to the cathode of the first LED string.
Active-Low Reset Input. Pulse RESET_IN low to reset all registers (except STATUS and EVENT) to
their default state.
Clock Input for I 2 C Serial Interface. High impedance when the I 2 C interface is off.
Enable Input for LDO1. Drive LDO1_EN high to enable LDO1, or low to disable LDO1. Once LDO1 is
enabled or disabled through I 2 C, the state of LDO1_EN is ignored until reset.
Compensation for OUT1 Step-Up Converter. Connect a 2200pF capacitor from COMP1 to ground.
See the Soft-Start OUT1 section for more details.
