Description
VDDQ regulator enable input. High to enable.
VTT regulator enable input. High to enable.
Forced PWM enable input. Low to enable forced PWM mode and disable power?saving mode.
VDDQ Soft?start capacitor connection to ground.
Power ground for the VTT regulator.
VTT regulator output.
Power input for VTT regulator which is normally connected to the VDDQ output of the buck regulator.
VTT regulator feedback pin for closed loop regulation.
Analog ground connection and remote ground sense.
External reference input which is used to regulate VTT and VTTREF to 1/2VDDQREF.
5.0 V supply input for the IC’s control and logic section, which is monitored by undervoltage lock out
circuitry.
VDDQ error amplifier compensation node.
VDDQ regulator feedback pin for closed loop regulation.
DDR reference voltage output.
Power good signal open?drain output.
Overcurrent sense and program input for the high?side FET of VDDQ regulator. Also the battery voltage
input for the internal ramp generator to implement the voltage feedforward rejection to the input voltage
variation. This pin must be connected to the VIN through a resistor to perform the current limit and volt-
age feedforward functions.
Positive supply input for high?side gate driver of VDDQ regulator and boost capacitor connection.
Gate driver output for VDDQ regulator high?side N?Channel power FET.
VDDQ regulator inductor driven node, return for high?side gate driver, and current limit sense input.
Power supply for the VDDQ regulator low?side gate driver and also supply voltage for the bootstrap
capacitor of the VDDQ regulator high?side gate driver supply.
Gate driver output for VDDQ regulator low?side N?Channel power FET.
Power ground for the VDDQ regulator.
Copper pad on bottom of IC used for heatsinking. This pin should be connected to the ground plane un-
der the IC.
