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 SW 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 SW and the output voltage.
Power Ground. Source of the low-side internal power MOSFET of Channel 2.
Power Ground. Source of the low-side internal power MOSFET of Channel 2.
Power Ground. Source of the low-side internal power MOSFET of Channel 1.
Power Ground. 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 connect the output LC filter between SW 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 and drive EN1 low to turn off
Channel 1. Tie EN1 to VDD for startup with VDD. With multiphase configurations, connect EN1 to EN2.
Open-Drain Power Good Output for Channel 1. Place a 100 kΩ pull-up resistor to VDD or any other voltage ≤ 5.5 V;
PGOOD1 pulls 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. Connect this pin through a resistor to GND or tie to VDD 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) or an adjustable output voltage for V
for output voltage selection.
Feedback Voltage Input for Channel 1. For the fixed output voltage option, connect FB1 to V
adjusted output voltage option, connect this pin to a resistor divider between V
configurations, connect FB1 to FB2 and then connect them to V
Exposed Thermal Pad. Connect to the signal/analog ground plane.
