Description
Switching Node .
Power Input Voltage . Connect to the main input power source.
Power Ground . Power return and Q2 source.
High-side Drive BOOT Voltage . Connect through capacitor (C BOOT ) to SW. The IC includes
an internal synchronous bootstrap diode to recharge the capacitor on this pin to V CC when
SW is LOW.
Power-Good Flag . An open-drain output that pulls LOW when FB is outside a ±10% range
of the reference when EN is HIGH. PGOOD does not assert HIGH until the fault latch is
enabled.
ENABLE . Enables operation when pulled to logic HIGH or left open. Toggling EN resets the
regulator after a latched fault condition. This input has an internal pull-up when the IC is
functioning normally. When a latched fault occurs, EN is discharged by a current sink.
Input Bias Supply for IC . The IC’s logic and analog circuitry are powered from this pin.
Analog Ground . The signal ground for the IC. All internal control voltages are referred to
this pin. Tie this pin to the ground island/plane through the lowest impedance connection.
Current Limit . A resistor (R ILIM ) from this pin to AGND can be used to program the current-
limit trip threshold lower than the default setting.
Oscillator Frequency . A resistor (R T ) from this pin to AGND sets the PWM switching
frequency.
Output Voltage Feedback . Connect through a resistor divider to the output voltage.
Compensation . Error amplifier output. Connect the external compensation network between
this pin and FB.
No Connect . This pin is not used.
Ramp Amplitude . A resistor (R RAMP ) connected from this pin to VIN sets the ramp amplitude
and provides voltage feedforward functionality.
