bypass to PGND2 with a minimum total capacitance of 10μF. The total capacitance can
include input bypass capacitors cascaded from OUT2, discharged by a 70 Ω resistance
between OUTS2 and PGND2 when disabled.

Power Ground for BUCK 2. Connect PGND2 and GND_ together near the device.
Inductor Connection for OUT2. Connect a 2.2μH inductor between LX2 and OUT2 as shown
in the Functional Diagram .
OUT2 Supply Input. Connect a 4.7μF or larger ceramic capacitor from PV2 to ground.
Linear-Regulator Power Input for OUT3. Bypass PV3 to GND with a minimum 2.2μF ceramic
capacitor.
Linear-Regulator 1 Output. Bypass OUT3 to GND with a minimum 2.2μF ceramic capacitor
internally discharged by a 1k Ω resistance when disabled.
Ground. Connect GND, GND1, GND2, and GND3 together.
Linear-Regulator 2 Output. Bypass OUT4 to GND with a minimum 2.2μF ceramic capacitor.
Internally discharged by a 1k Ω resistance when disabled.
Linear-Regulator Power Input for OUT4. Bypass PV4 to GND with a minimum 2.2μF ceramic
capacitor.
5V Logic Supply to Provide Power to Internal Circuitry. Bypass LSUP to GND1 with a 1μF
ceramic capacitor.
Open-Drain Reset Output for the Input Monitoring OUT1 and OUT2. External pullup
required.
Ground. Connect GND, GND1, GND2, and GND3 together.
Active-High Enable Input. Connect EN to PV1 or a logic-high voltage to turn on all
regulators. Pull EN input low to place the regulators in shutdown.
Exposed Pad. Connect the exposed pad to ground. Connecting the exposed pad to ground
EP
does not remove the requirement for proper ground connections to PGND2 and GND_. The
exposed pad is attached with epoxy to the substrate of the die, making it an excellent path
to remove heat from the device.
