Pin No. Mnemonic Description
24, 25 SW1 Switch Node for Channel 1.
26, 27 PVIN1 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 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.
29 TRK1 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.
30 SS1 Soft Start Control for Channel 1. To program the soft start time, connect a capacitor from SS1 to GND.
31 COMP1 Error Amplifier Output for Channel 1. Connect an RC network from COMP1 to GND. Connect COMP1 and COMP2
together for parallel applications.
32
FB1
Feedback Voltage Sense Input for Channel 1. Connect FB1 to a resistor divider from the Channel 1 output voltage, V
OUT1
