Description
Power Good pin out put for channel 1, open collector. This pin
needs to be externally pulled high
Power Good pin out put for channel 2, open collector. This pin
needs to be externally pulled high
Sets the type of power up / down sequencing (ratiometric or
simultaneously). If it is not used connect this pin to Vout3.
Sense pin for OVP2 and Power Good 2, Channel 2. If it is not used
connect this pin to Gnd.
OVP output, goes high when OVP condition occurs
Inverting inputs to the error amplifier2. If it is not used connect this
pin to Gnd
Compensation pin for the error amplifier2
Soft start for channel 2, can be used as SD pin. Float this pin for
current share single output application. If it is not used connect this
pin to Gnd.
Current limit set point for channel2
Phase Enable pin for channel2
PWM output for channel2
Supply Voltage for the internal blocks of the IC
Output of the internal regulator
PWM output for channel1
Phase Enable pin for channel1
Current limit set point for Channel 1
Soft start for channel 1, can be used as SD pin
Compensation pin for the error amplifier1
Inverting input to the error amplifier1
Ground connection for OCset circuit
Sense pin for OVP1 and Power Good, Channel 1
Sets the type of power up / down sequencing (ratiometric or
simultaneously). If it is not used connect this pin to Vout3.
External synchronization pin
Enable pin for tracking and sequencing
Non inverting input of error amplifier1
Non inverting input of error amplifier2. If it is not used connect this
pin to Gnd.
Reference Voltage
Signal Ground
IC’s Ground
Connecting a resistor from this pin to ground sets the Switching
frequency
Enable pin, recycling this pin will rest OV, SS and Prebias latch
Sensing either external 5V or the Vout3
