Data Sheet
Pin No. Mnemonic Description
24, 25
26, 27
SW1
PVIN1
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.
28
29
EN1
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.
TRK1
30
31
SS1
COMP1
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.
32
N/A1
FB1
EP
Feedback Voltage Sense Input for Channel 1. Connect FB1 to a resistor divider from the Channel 1 output voltage, VOUT1
Exposed Pad. Solder the exposed pad to an external GND plane.
