Description
Thermal Throttling Sense and Crowbar Disable Input. A resistor divider where the upper resistor is connected
to VCC, the lower resistor (NTC thermistor) is connected to GND, and the center point is connected to this
pin and acts as a temperature sensor half bridge. Connecting TTSNS to GND disables the thermal throttling
function and disables the crowbar, or Overvoltage Protection (OVP), feature of the chip.
Analog and Digital Signal Ground.
This pin sets the internal bias currents. A 80 k W resistor is connected from this pin to ground.
RPM Mode Timing Control Input. A resistor between this pin to ground sets the RPM mode turn ? on
threshold voltage.
Multi ? phase Frequency Setting Input. An external resistor connected between this pin and GND sets the
oscillator frequency of the device when operating in multi ? phase PWM mode threshold of the converter.
PWM Ramp Slope Setting Input. An external resistor from the converter input voltage node to this pin sets
the slope of the internal PWM stabilizing ramp used for phase ? current balancing.
Output Load Line Programming Input. The center point of a resistor divider between CSREF and
CSCOMP is connected to this pin to set the load line slope.
Current Sense Reference Input. This pin must be connected to the common point of the output inductors.
The node is shorted to GND through an internal switch when the chip is disabled to provide soft stop
transient control of the converter output voltage.
Current Sense Summing Input. External resistors from each switch node to this pin sum the inductor
currents to provide total current information.
Current Sense Compensation Point. A resistor and capacitor from this pin to CSSUM determine the gain of
the current ? sense amplifier and the positioning loop response time.
Current Limit Setpoint. An external resistor from this pin to CSCOMP sets the current limit threshold of the
converter.
Multi ? phase Output Disable Logic Output. This pin is actively pulled low when the APD3212/NCP3218/
NCP3218G enters single ? phase mode or during shutdown. Connect this pin to the SD inputs of the
Phase ? 3 MOSFET drivers.
Logic ? Level PWM Output for phase 3. Connect to the input of an external MOSFET driver such as the
ADP3611.
Current Balance Input for phase 3. Input for measuring the current level in phase 3. SWFB3 should be left
open for 1 or 2 phase configuration.
High ? Side Bootstrap Supply for Phase 2. A capacitor from this pin to SW2 holds the bootstrapped voltage
while the high ? side MOSFET is on.
High ? Side Gate Drive Output for Phase 2.
Current Return for High ? Side Gate Drive for phase 2.
Current Balance Input for phase 2. Input for measuring the current level in phase 2. SWFB2 should be left
open for 1 phase configuration.
Low ? Side Gate Drive Output for Phase 2.
Low ? Side Driver Power Ground
Low ? Side Gate Drive Output for Phase 1.
Power Supply Input/Output of Low ? Side Gate Drivers.
Current Balance Input for phase 1. Input for measuring the current level in phase 1.
Current Return For High ? Side Gate Drive for phase 1.
High ? Side Gate Drive Output for Phase 1.
High ? Side Bootstrap Supply for Phase 1. A capacitor from this pin to SW1 holds the bootstrapped voltage
while the high ? side MOSFET is on.
Power Supply Input/Output of the Controller.
Phase Number Configuration Input. Connect to VCC for 3 phase configuration.
Phase Number Configuration Input. Connect to GND for 1 phase configuration. Connect to VCC for
multi ? phase configuration.
Deeper Sleep Control Input.
Power State Indicator Input. Pulling this pin to GND forces the APD3212/NCP3218/NCP3218G to operate
in single ? phase mode.
Voltage Identification DAC Inputs. When in normal operation mode, the DAC output programs the FB
regulation voltage from 0.3 V to 1.5 V (see Table 3).
