Leave floating for input voltages >3.5V. Externally, add a 2.2μF
capacitor
Internally generated voltage. Connect to pin A when Vin < 3.5V.
Leave floating for input voltages >3.5V. Externally, add a 2.2μF
capacitor
Output of the first error amplifier, refer to Fig.1 block diagram
Output of the second error amplifier
Single pin for both outputs. Commands outputs ON or OFF. Pulled
low, turns both outputs ON. Should be pulled high to disable outputs.
Soft start pin for output1. External capacitor
provides soft start. Pulled low disables output 1.
Soft start pin for output2. External capacitor
provides soft start. Pulled low disables output 2.
Inverting input of error amplifier 1
Output 1 voltage sense pin
Inverting input of error amplifier 2
Output 2 voltage sense pin
Output 1 inductor connection node
Output 2 inductor connection node
Power Ground
Amplifier 1 reference Voltage. Connect a 100pf cap from this pin to
PGND.
Amplifier 2 reference voltage. Connect to Vref for independent
output configuration. Refer to function description section on how to
connect for parallel configuration.
External Clock synchronization pin. Set free running frequency to
80% of the SYNC frequency. When not in use leave pin floating.
Switching frequency setting pin. For R T selection, refer to Fig.11 R T
vs Frequency curve.
Power Good pin, needs external pull-up resistor. If not used pin can
be left floating.
Logic level pin. Pulled high enables hiccup mode of operation. Pulled
low enables overcurrent shutdown mode.
Unused pin. No electrical connection.
* Part will malfunction if pins A and B are shorted together for input voltages >3.5V
