Source Input Voltage
Inverting input to the error amplifier The non-inverting input is internally connected to a 1.25 Volt
reference.
Output to the error amplifier
There is an internal 5K resistor pull-up on this pin. The error
amplifier provides an active sink.
Output from the internal high
voltage series pass regulator. The
regulation setpoint is 7.7 Volts.

Output of the PWM controller
Alternating PWM output gate driver.
Output of the PWM controller
Alternating PWM output gate driver.

Current sense input
Current sense input for current mode control and current limit
sensing. Using separate dedicated comparators, if CS exceeds
0.5 Volt the outputs will go into Cycle by Cycle current limit. If CS
exceeds 0.625V the outputs will be disabled and a softstart
commenced.
