FUNCTION
Buck Converter Feedback Input. FBB is regulated to either 3.3V or 5V. Connect FBB to the output-volt-
age node, OUTB, as shown in the Typical Application Circuit .
Buck Converter Internal 5V Regulator. Connect a 1 F F capacitor between AVL and the analog ground
plane. Do not use AVL to power external circuitry.
Buck Converter Bootstrap Capacitor Connection. Connect a 0.1 F F capacitor between BST and LXB.
Buck Converter Inductor Connection. Connect the inductor, boost capacitor, and catch diode at this
node.
Buck Converter Power Input. Connect to a 4V to 28V supply. Connect a 1 F F or larger ceramic capaci-
tor in parallel with a 47 F F bulk capacitor from INB to the power ground plane. Connect both INB power
inputs together.
Buck Converter Enable Input. ENB is a high-voltage compatible input. Connect to INB for normal opera-
tion and connect to ground to disable the buck converter.
Analog Ground
Open-Drain Power-Good Output. Connect PGOOD to INA through an external pullup resistor.
Positive-Gate Voltage Regulator Power Input. Connect CP to the positive output of the external charge
pump. Ensure that V CP does not exceed the CP overvoltage threshold as given in the Electrical
Characteristics table.
Positive-Gate Voltage Regulator Output
Negative-Gate Voltage Regulator Driver Output. DRVN is the open drain of an internal p-channel FET.
Connect DRVN to the base of an external npn pass transistor.
Boost Slope Compensation Connection. Connect a capacitor between COMPI and GND to set the
slope compensation.
Positive-Gate Voltage Regulator Feedback Input. FBGH is regulated to 1V. Connect FBGH to the center
of a resistive divider connected between GH and GND.
Negative-Gate Voltage Regulator Feedback Input. FBGL is regulated to 0.25V. Connect FBGL to the
center of a resistive divider connected between REF and the output of the negative-gate voltage
regulator.
1.25V Reference Output. Bypass REF to GND with a 0.1 F F ceramic capacitor.
Sequencing Input. SEQ has an internal 500k I pulldown resistor. SEQ determines the sequence in
which V GH and V GL power-up. See Table 1 for supply sequencing options.
Exposed Pad. Connect to a large contiguous copper ground plane for optimal heat dissipation. Do not
use EP as the only electrical ground connection.
