Pin Descriptions
Pin Name
Pin No.
Description
FB
1
This pin is connected directly to the output of the switching regulator via resistor
divider to provide feedback to the Error amplifier.
Vcc
2
This pin provides biasing for the internal blocks of the IC as well as power for the
low side driver. A minimum of 1uF, high frequency capacitor must be connected
from this pin to ground to provide peak drive current capability.
LDrv
3
Output driver for the synchronous power MOSFET.
GND
4
This pin serves as the ground pin and must be connected directly to the ground
plane. A high frequency capacitor (0.1 to 1uF) must be connected from V5 and
V12 pins to this pin for noise free operation.
HDrv
5
Output driver for the high side power MOSFET.
Vc
6
This pin is connected to a voltage that must be at least 4V higher than the bus
voltage of the switcher (assuming 5V threshold MOSFET) and powers the high
side output driver. A minimum of 1uF, high frequency capacitor must be
connected from this pin to ground to provide peak drive current capability.
Comp
7
Compensation pin of the error amplifier. An external resistor and capacitor
network is typically connected from this pin to ground to provide loop
compensation.
SS
8
This pin provides soft-start for the switching regulator. An internal current source
charges an external capacitor that is connected from this pin to ground which
ramps up the output of the switching regulator, preventing it from overshooting as
well as limiting the input current. The converter can be shutdown by pulling this
pin below 0.5V.
