Pin Function Description
Connect this pin to the gate of an N-channel MOSFET. The
trace from this pin to the MOSFET gate should be <0.5".
High Side Driver Source and Low Side Driver Drain Switching Node.
with DROOP and ILIM pins allows FET sensing for V
Analog Ground.
Return path for low power analog circuitry. This pin should be
connected to a low impedance system ground plane to minimize ground loops.
Voltage Identification Code Inputs.
These open collector/TTL compatible inputs
will program the output voltage over the ranges specified in Table 1. Pull-up
resistors are internal to the controller.
Gate Driver for VADJ Transistor.
For Adjustable output.
Voltage Feedback for VADJ.
Gate Driver for VCK Transistor.
For 2.5V output.
Voltage Feedback for VCK.
Voltage Feedback for VAGP.
Gate Driver for VAGP Transistor.
For 3.3/1.5V output.
Type Detect.
Sets 3.3V or 1.5V for AGP.
Output Enable.
A logic LOW on this pin will disable all outputs. An internal current
source allows for open collector control. This pin also doubles as soft start for all
outputs.
Power Good Flag.
An open collector output that will be logic LOW if any output
voltage is not within ±14% of the nominal output voltage setpoint.
V

Current Feedback.
Pin 18 is used in conjunction with pin 2 as the input for the
V
CC
current feedback control loop. Layout of these traces is critical to system
performance. See Application Information for details.
Droop Set.
Use this pin to set magnitude of active droop.
Vcc Voltage Feedback.
Pin 20 is used as the input for the V
control loop. See Application Information for details regarding correct layout.
