Description
Power Supply Input. The source of the high-side internal power MOSFET of Channel 2.
Power Supply Input. The source of the high-side internal power MOSFET of Channel 2.
Power Supply Input. The source of the high-side internal power MOSFET of Channel 2.
Switch Node Output. The drain of the P-channel power switch and N-channel synchronous rectifier of Channel 2.
Tie SW3 to SW4, and then connect the output LC filter between the switching node and the output voltage.
Switch Node Output. The drain of the P-channel power switch and N-channel synchronous rectifier of Channel 2.
Tie SW3 to SW4, and then connect the output LC filter between the switching node and the output voltage.
Power Ground. The source of the low-side internal power MOSFET of Channel 2.
Power Ground. The source of the low-side internal power MOSFET of Channel 2.
Power Ground. The source of the low-side internal power MOSFET of Channel 1.
Power Ground. The source of the low-side internal power MOSFET of Channel 1.
Switch Node Output. The drain of the P-channel power switch and N-channel synchronous rectifier of Channel 1.
Tie SW1 to SW2, and then connect the output LC filter between the switching node and the output voltage.

Power Supply Input. The source of the high-side internal power MOSFET of Channel 1.
Power Supply Input. The source of the high-side internal power MOSFET of Channel 1.
Enable Input for Channel 1. Drive EN1 high to turn on the Channel 1 converter; drive EN1 low to turn off the Channel 1
converter. Tie EN1 to VDD for startup with VDD. When using a multiphase configuration, connect EN1 to EN2.
Open-Drain Power-Good Output for Channel 1. Place a 100 kΩ pull-up resistor to VDD or to any other voltage that is
5.5 V or less; PGOOD1 is held low when Channel 1 is out of regulation.
Soft Start Input for Channel 1. Place a capacitor from SS1 to GND to set the soft start period. A 10 nF capacitor
sets a 1 ms soft start period. For multiphase configuration, connect SS1 to SS2.
Output Voltage Set Pin for Channel 1. To select a fixed output voltage option (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V)

Feedback Voltage Input for Channel 1. For the fixed output voltage option, connect FB1 to V
output voltage option, connect this pin to a resistor divider between V
configurations, the FB1 and FB2 pins should be tied together and then connected to V
Exposed Thermal Pad. Connect the exposed thermal pad to the signal/analog ground plane.
