Pin Definitions
Pin #
Name
Description
P1, 6-12
SW
Switching Node. Junction of high-side and low-side MOSFETs.
P2, 2-5
VIN
Power Input Voltage. Connect to the main input power source.
P3, 21-23
PGND
Power Ground. Power return and Q2 source.
High-Side Drive BOOT Voltage. Connect through capacitor (C

BOOT
includes an internal synchronous bootstrap diode to recharge the capacitor on this pin to
V
when SW is LOW.
CC
Power-Good Flag. An open-drain output that pulls LOW when FB is outside the limits
13
PGOOD
specified in electrical specs. 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
14
EN
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.
15
VCC
This pin should be decoupled to AGND through a >1µF X5R/X7R capacitor.
Analog Ground. The signal ground for the IC. All internal control voltages are referred to
16
AGND
this pin. Tie this pin to the ground island/plane through the lowest impedance connection.
Current Limit. A resistor (R

ILIM
limit trip threshold lower than the default setting.
Oscillator Frequency. A resistor (R

R(T)
frequency.
19
FB
Output Voltage Feedback. Connect through a resistor divider to the output voltage.
Compensation. Error amplifier output. Connect the external compensation network
20
COMP
between this pin and FB.

NC
No Connect. This pin is not used.
Ramp Amplitude. A resistor (R
