Pin Assignments
Pin Definitions
Pin Number
Pin Name
Pin Function Description
1
ROSC
Oscillator Resistor Connection. Connect an external resistor to this pin to set
the internal oscillator frequency. Layout of this pin is critical to system
performance. See Application Information for details.
2
ENABLE/SS
Output Enable/Softstart. A logic LOW on this pin will disable the output. An
internal current source allows for open collector control. This pin also doubles as
soft start.
3
PWRGD
Power Good Flag. An open collector output that will be logic LOW if the output
voltage is not within ±12% of the nominal output voltage setpoint.
4
IFB
Current Feedback. Pin 4 is used in conjunction with pin 13, as the input for the
current feedback control loop. Layout of these traces is critical to system
performance. See Application Information for details.
5
VFB
Voltage Feedback. Pin 5 is used as the input for the voltage feedback control
loop. See Application Information for details regarding correct layout.
6
VCCA
Analog VCC. Connect to system 5V supply and decouple with a 0.1µF ceramic
capacitor.
7OVP
Over Voltage Protection. This pin triggers the gate of an external SCR.
8
GNDP
Power Ground. Return pin for high currents flowing in pins 10 and 11. Connect
to a low impedance ground.
9
LODRV
Low Side FET Driver. Connect this pin to the gate of an N-channel MOSFET for
synchronous operation. The trace from this pin to the MOSFET gate should be
<0.5".
10
VCCP
Power VCC. For low side FET driver. Connect to system 12V supply and
decouple with a 10
Ω resistor, 4.7µF tantalum and a 0.1µF ceramic capacitor.
11
VCCQP
High Side Power VCC. For high side FET driver. Connect to system 12V supply
and decouple with a 10
Ω resistor, 4.7µF tantalum and a 0.1µF ceramic capacitor.
12
HIDRV
High Side FET Driver. Connect this pin to the gate of an N-channel MOSFET.
The trace from this pin to the MOSFET gate should be <0.5".
13
SW
High side driver source and low side driver drain switching node. Together
with IFB pin allows FET sensing for current.
14
GNDA
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.
15
DTA
Dead Time Adjust. Connect an external resistor to this pin to set the dead time.
16–20
VID0-4
Voltage Identification Code Inputs. These open collector/TTL compatible inputs
will program the output voltage over the ranges specified in Table 2. Pull-up
resistors are internal to the controller.
