These pins provide feedback for the linear regulator controllers.
Outputs of the linear regulator controllers.
A resistor should be connected from this pin to ground for setting the switching frequency.
This pin provides soft-start for the switching regulator. An internal current source charges
an external capacitor that is connected from this pin to ground which ramps up the output
of the switching regulator, preventing it from overshooting as well as limiting the input
current. The converter can be shutdown by pulling this pin down below 0.4V.
Compensation pin of the error amplifier. An external resistor and capacitor network is
typically connected from this pin to ground to provide loop compensation.
This pin is connected directly to the output of the switching regulator via resistor divider to
provide feedback to the Error amplifier.
Non-inverting input of error amplifier.
Reference voltage.
This pin provides biasing for the internal blocks of the IC as well as powers the LDO
controller. A minimum of 1
μ
F, high frequency capacitor must be connected from this pin
to ground to provide peak drive current capability.
This pin powers the low side output driver and can be connected either to Vcc or separate
supply. A minimum of 1
μ
F, high frequency capacitor must be connected from this pin to
ground to provide peak drive current capability.
Output driver for the synchronous power MOSFET.
