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.
Forced PWM Mode . When logic LOW, inhibits the regulator from entering Hysteretic Mode;
otherwise tie to V OUT . The regulator uses V OUT on this pin to ensure a smooth transition from
Hysteretic Mode to PWM Mode. When V OUT is expected to exceed V CC , tie to V CC .
Output Voltage Sense . The feedback from the outputs. Used for regulation as well as PG,
under-voltage, and over-voltage protection and monitoring.
Current Limit 1 . A resistor from this pin to GND sets the current limit.
Soft Start . A capacitor from this pin to GND programs the slew rate of the converter during
initialization. During initialization, this pin is charged with a 5mA current source.
