PIN FUNCTION DESCRIPTION
Pin Symbol Description
1 VDDQEN VDDQ regulator enable input. High to enable.
2 VTTEN VTT regulator enable input. High to enable.
3 FPWM Forced PWM enable input. Low to enable forced PWM mode and disable power−saving mode.
4 SS VDDQ Soft−start capacitor connection to ground.
5 VTTGND Power ground for the VTT regulator.
6 VTT VTT regulator output.
7 VTTI Power input for VTT regulator which is normally connected to the VDDQ output of the buck regulator.
8 FBVTT VTT regulator feedback pin for closed loop regulation.
9 AGND Analog ground connection and remote ground sense.
10 DDQREF External reference input which is used to regulate VTT and VTTREF to 1/2VDDQREF.
11 VCCA 5.0 V supply input for the IC’s control and logic section, which is monitored by undervoltage lock out
circuitry.
12 COMP VDDQ error amplifier compensation node.
13 FBDDQ VDDQ regulator feedback pin for closed loop regulation.
14 VTTREF DDR reference voltage output.
15 PGOOD Power good signal open−drain output.
16 OCDDQ
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.
17 BOOST Positive supply input for high−side gate driver of VDDQ regulator and boost capacitor connection.
18 TGDDQ Gate driver output for VDDQ regulator high−side N−Channel power FET.
19 SWDDQ VDDQ regulator inductor driven node, return for high−side gate driver, and current limit sense input.
20 VCCP 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.
21 BGDDQ Gate driver output for VDDQ regulator low−side N−Channel power FET.
22 PGND Power ground for the VDDQ regulator.
23 THPAD Copper pad on bottom of IC used for heatsinking. This pin should be connected to the ground plane un-
der the IC.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
