PIN FUNCTIONS
QFN
Pin #
SOIC8
Pin #
Name
Description
1, 2
1
SW
Switch Node. This is the output from the high-side switch. A low forward drop
Schottky diode to ground is required. The diode must be close to the SW pins to
reduce switching spikes.
3
2
EN
Enable Input. Pulling this pin below the specified threshold shuts the chip down.
Pulling it up above the specified threshold or leaving it floating enables the chip.
4
3
COMP
Compensation. This node is the output of the error amplifier. Control loop frequency
compensation is applied to this pin.
5
4
FB
Feedback. This is the input to the error amplifier. The output voltage is set by a
resistive divider connected between the output and GND which scales down VOUT
equal to the internal +0.8V reference.
6
5
GND,
Exposed
Pad*
Ground. It should be connected as close as possible to the output capacitor to
shorten the high current switch paths. Connect exposed pad (QFN Package Only) to
ground plane.
7
6
FREQ
Switching Frequency Program Input. Connect a resistor from this pin to ground to set
the switching frequency.
8, 9
7
VIN
Input Supply. This supplies power to all the internal control circuitry, both BST
regulators and the high-side switch. A decoupling capacitor to ground must be placed
close to this pin to minimize switching spikes.
10
8
BST
Bootstrap. This is the positive power supply for the internal floating high-side
MOSFET driver. Connect a bypass capacitor between this pin and SW pin.
* Note: exposed pad applies to QFN package only.
