FUNCTION
Track/Sequence Select Input. Connect SEL to SGND to configure the device as a sequencer. Connect
SEL to AVIN for tracking with output 1 as the master. Leave SEL unconnected for tracking with output 2
as the master. Use the output with the higher voltage as the master and the output with the lower voltage
as the slave.
Power Ground Connection for Regulator 1. Connect the negative terminals of the input and output filter
capacitors to PGND1. Connect PGND1 externally to SGND at a single point, typically at the negative
terminal of the input bypass capacitor.
Inductor Connection for Regulator 1. LX1 is the drain connection of the internal high-side p-channel
MOSFET and the drain connection of the internal synchronous n-channel MOSFET for regulator 1.
Input Supply Voltage for Regulator 1. Connect PVIN1 to an external voltage source from 2.5V to 5.5V.
Bypass PVIN1 to PGND1 with a 1μF (min) ceramic capacitor.
Switch Driver Supply for Regulator 1. Connect externally to PVIN1.
Enable Input for Regulator 1. When configured as a sequencer, EN1 must exceed 1.225V (typ) for the
PWM controller to begin regulating output 1. When configured as a tracker, connect EN1 to the center
tap of a resistive divider from the regulator 2 output.
Feedback Regulation Point for Regulator 1. Connect FB1 to the center tap of a resistive divider from the
regulator 1 output to SGND to set the output voltage. The FB1 voltage regulates to 0.6V (typ).
Error-Amplifier Output for Regulator 1. Connect COMP1 to the compensation feedback network.
