Description
Analog Ground . This is the signal ground reference for the IC. All voltage levels are measured
with respect to this pin
Low-Side Drive . The low-side (lower) MOSFET driver output. Connect to gate of low-side
MOSFET.
Power Ground . The return for the low-side MOSFET driver. Connect to source of low-side
MOSFET.
Switching Node . Return for the high-side MOSFET driver and a current sense input. Connect
to source of high-side MOSFET and low-side MOSFET drain.
High-Side Drive . High-side (upper) MOSFET driver output. Connect to gate of high-side
MOSFET.
BOOT . Positive supply for the upper MOSFET driver. Connect as shown in Figure 4.
Current-Sense Input . Monitors the voltage drop across the lower MOSFET or external sense
resistor for current feedback.
Enable . Enables operation when pulled to logic HIGH. Toggling EN resets the regulator after a
latched fault condition. These are CMOS inputs whose state is indeterminate if left open.
Ground
Output Voltage Sense . The feedback from the outputs; used for regulation as well as PG,
under-voltage, and over-voltage protection and monitoring.
