FUNCTION
Bootstrap Capacitor Input. Connect a 0.1μF ceramic capacitor from BST to LX1.
OUT1 Supply Input. Connect a 4.7μF or larger ceramic capacitor from PV1 to PGND.
Inductor Connection for OUT1. Connect a 4.7μH inductor between LX1 and OUTS1, and a

GND3
Ground. Connect GND, GND1, GND2, and GND3 together.
OUT1 Voltage-Sensing Input. Connect OUTS1 directly to the OUT1 output voltage and

OUTS1
bypass to power-ground plane with a minimum total capacitance of 15μF. The total
capacitance can include input bypass capacitors cascaded from OUT1, discharged by a
70 Ω resistance between OUTS1 and GND3 when disabled.
PWM Control Input. Connect PWM to OUTS1 to force LX2 to switch every cycle. Connect

PWM
PWM to high for forced-PWM operation on OUT2. Connect low for auto-PWM operation to
improve efficiency at light loads.
