Description
1 to 6
VID4 to VID0,
VID5
Voltage Identification DAC Inputs. These six pins are pulled up to an internal reference, providing a Logic 1
if left open. When in normal operation mode, the DAC output programs the FB regulation voltage from
0.8375 V to 1.6 V (see Table 2). Leaving all the VID pins open results in ADP3190/ADP3190A going into a
“No CPU” mode, shutting off their PWM outputs and pulling the PWRGD output low.
7
FBRTN
Feedback Return. VID DAC and error amplifier reference for remote sensing of the output voltage.
8
FB
Feedback Input. Error amplifier input for remote sensing of the output voltage. An external resistor between
this pin and the output voltage sets the no-load offset point.
9
COMP
Error Amplifier Output and Compensation Point.
10
PWRGD
Power Good Output. Open drain output that signals when the output voltage is outside of the proper
operating range.
11
EN
Power Supply Enable Input. Pulling this pin to GND disables the PWM outputs and pulls the PWRGD output
low.
12
DELAY
Soft start Delay and Current-Limit Latch-off Delay Setting Input. An external resistor and capacitor
connected between this pin and GND sets the soft start ramp-up time and the overcurrent latch-off delay
time.
13
RT
Frequency Setting Resistor Input. An external resistor connected between this pin and GND sets the
oscillator frequency of the device.
14
RAMPADJ
PWM Ramp Current Input. An external resistor from the converter input voltage to this pin sets the internal
PWM ramp.
15
ILIMIT
Current Limit Set Point/Enable Output. An external resistor from this pin to GND sets the current limit
threshold of the converter. This pin is actively pulled low when the ADP3190/ADP3190A EN input is low or
when VCC is below its UVLO threshold to signal to the driver IC that the driver high-side and low-side
outputs should go low.
16
CSREF
Current Sense Reference Voltage Input. The voltage on this pin is used as the reference for the current sense
amplifier and the power good and crowbar functions. This pin should be connected to the common point of
the output inductors.
17
CSSUM
Current Sense Summing Node. External resistors from each switch node to this pin sum the average inductor
currents together to measure the total output current.
18
CSCOMP
Current Sense Compensation Point. A resistor and capacitor from this pin to CSSUM determine the slope of
the load line and the positioning loop response time.
19
GND
Ground. All internal biasing and the logic output signals of the device are referenced to this ground.
20 to 23
SW4 to SW1
Current Balance Inputs. Inputs for measuring the current level in each phase. The SW pins of unused phases
should be left open.
24 to 27
PWM4 to PMW1
Logic Level PWM Outputs. Each output is connected to the input of an external MOSFET driver such as the
ADP3120A. Connecting the PWM3 and/or PWM4 outputs to GND causes that phase to turn off, allowing the
ADP3190/ADP3190A to operate as a 2-, 3-, or 4-phase controller.
28
VCC
ADP3190: A 240 Ω resistor should be placed between the 12 V system supply and the VCC pin to ensure 5 V.
ADP3190A: A 10 Ω resistor should be placed between the 5 V system supply and the VCC pin to ensure 5 V.
