PIN NAME DESCRIPTION
V
CC
Bias Supply Input. Connect to external 5V supply. Used to power internal circuits and
low side gate driver.
GL
High current driver output for the low side NFET switch. It is always low if GH is high or
during a fault. Resistor pull down ensure low state at low voltage.
GND
Ground Pin. The control circuitry of the IC and lower power driver are referenced to this
pin. Return separately from other ground traces to the (-) terminal of C
OUT
.
V
FB
Feedback Voltage and Short Circuit Detection pin. It is the inverting input of the Error
Amplifier and serves as the output voltage feedback point for the Buck Converter. The
output voltage is sensed and can be adjusted through an external resistor divider.
Whenever V
drops 0.25V below the positive reference, a short circuit fault is detected
and the IC enters hiccup mode.
COMP
Output of the Error Amplifier. It is internally connected to the non-inverting input of the
PWM comparator. An optimal filter combination is chosen and connected to this pin and
either ground or V
FB
to stabilize the voltage mode loop.
UVIN
UVLO input for V
voltage. Connect a resistor divider between V
IN
and UVIN to set
minimum operating voltage.
SS
Soft Start. Connect an external capacitor between SS and GND to set the soft start rate
based on the 10
μ
A source current. The SS pin is held low via a 1mA (min) current during
all fault conditions.
SWN
Lower supply rail for the GH high-side gate driver. Connect this pin to the switching node
at the junction between the two external power MOSFET transistors.
GH
High current driver output for the high side NFET switch. It is always low if GL is high or
during a fault. Resistor pull down ensure low state at low voltage.
BST
High side driver supply pin. Connect BST to the external boost diode and capacitor as
shown in the Typical Application Circuit on page 1. High side driver is connected between
BST pin and SWN pin.
