Pin Function Description
Oscillator capacitor connection.
the internal oscillator frequency from 200 KHz to 1 MHz. Layout of this pin is critical to
system performance. See Application Information for details.
Power Good output flag.
Open collector output will be at logic HIGH under normal
operation. Logic LOW indicates output voltage is not within
High side current feedback.
Pins short 4 and 5 are used as the inputs for the current
feedback control loop and as the short circuit current sense points. Layout of these
traces is critical to system performance. See Application Information for details.
Voltage feedback.
Pin 5 is used as the input for the voltage feedback control loop and
as the low side current feedback input. Layout of this trace is critical to system
performance. See Application Information for details.

Connect to system 5V supply and decouple to ground with 0.1
ceramic capacitor.
Digital V
CC
.
Connect to system 5V supply and decouple to ground with 4.7
tantalum capacitor.
Power ground.
Return pin for high currents flowing in pins 8 and 9 (HIDRV and
VCCQP). Connect to low impedance ground. See Application Information for details.
FET driver output.
Connect this pin to the gate of the N-channel MOSFETs M1 and
M2 in Figures 1 and 2. The trace from this pin to the MOSFET gates should be kept as
short as possible (less than 0.5"). See Application Information for details.
Power V
CC
for FET Driver.
VCCQP must be connected to a voltage of at least
VCCA + V
GS,ON
(M1). See Application Information for details.
Digital ground.
Return path for digital logic. This pin should be connected to system
ground so that ground loops are avoided. See Application Information for details.
Analog ground.
Return path for low power analog circuitry. Connect to system ground
so that ground loops are avoided. See Application Information for details.
Reference voltage test point.
This pin provides access to the DAC output and
should be decoupled to ground using a 0.1
μ
to this pin.
Voltage identification (VID) code inputs.
These open collector/TTL compatible
inputs will program the output voltage over the ranges specified in Table 1.
