Description
Inverting input to the error amplifier. This pin is connected to the output of
the regulator via resistor divider to set the output voltage and provide
feedback to the error amplifier.
Dual function pin.
Non inverting input to the error amplifier.
Enable input.
No Connect
This pin provides power for the internal blocks of the IC as well as powers
the low side driver. A minimum of 0.1uF, high frequency capacitor must
be connected from this pin to power ground.
No Connect
Output driver for low side MOSFET.
IC ground for internal control circuitry.
Power Ground. This pin serves as a separate ground for the MOSFET
drivers and should be connected to the system’s power ground plane.
Output driver for high side MOSFET. The negative voltage at this pin may
cause instability for the gate drive circuit. To prevent this, a low forward
voltage drop diode (e.g. BAT54 or 1N4148) is required between this pin
and Power Ground.
This pin powers the high side driver.
No Connect
Output of error amplifier. An external resistor and capacitor network is
typically connected from this pin to ground to provide loop compensation.
Soft start. This pin provides user programmable soft-start function.
Connect an external capacitor from this pin to ground to set the start up
time of the output voltage.
No Connect
