Data Sheet
Description
Switch Node for Channel 1.
Power Input for Channel 1. These pins are the power inputs for Channel 1 and provide power for the internal
regulator. Connect to the input power source and connect a bypass capacitor between PVIN1 and ground.
Enable Pin for Channel 1. An external resistor divider can be used to set the turn-on threshold. When not using
the enable pin, connect EN1 to PVIN1.
Tracking Input for Channel 1. To track a master voltage, connect this pin to a resistor divider from the master
voltage. If the tracking function is not used, connect TRK1 to INTVCC.
Soft Start Control for Channel 1. To program the soft start time, connect a capacitor from SS1 to GND.
Error Amplifier Output for Channel 1. Connect an RC network from COMP1 to GND. Connect COMP1 and COMP2
together for parallel applications.
Feedback Voltage Sense Input for Channel 1. Connect FB1 to a resistor divider from the Channel 1 output voltage, V
OUT1
.
Exposed Pad. Solder the exposed pad to an external GND plane.
