Pin Functions

PIN I/O DESCRIPTION
NAME NO.
VLDOIN 1 P Power supply input for VTT LDO. Connect VDDQ in typical application.
VTT 2 O VTT 1-A LDO output. Recommend to connect to 10-μF or larger capacitance for stability.
AGND 3 G Signal ground.
VTTSNS 4 I VTT output voltage feedback.
VDDQSNS 5 I VDDQ output voltage feedback.
VTTREF 6 O Buffered VTT reference output. Recommend to connect to 0.22-μF or larger capacitance for stability.
PVIN 7 P Input power supply for VDDQ buck.
PGOOD 8 O Power good signal open-drain output. PGOOD goes high when VPP and VDDQ output voltage are within the target range.
PGND 9 G Power ground for VDDQ buck.
VTT_CNTL 10 I VTT_CNTL signal input for VTT LDO enable control. For detail control setup, please refer toTable 1.
SLP_S4 11 I SLP_S4 signal input for VDDQ buck and VPP buck enable control. For detail control setup, please refer toTable 1.
VPPSNS 12 I VPP output voltage feedback.
VCC_5V 13 P Power supply for VPP and VDDQ buck converter control logic circuit.
PVIN_VPP 14 P Input power supply for VPP buck.
SW_VPP 15 O VPP switching node connection to the inductor and bootstrap capacitor.
PGND_VPP 16 G Power ground for VPP buck.
SW 17 O VDDQ switching node connection to the inductor and bootstrap capacitor.
BST 18 I High-side MOSFET gate driver bootstrap voltage input for VDDQ buck. Connect a capacitor between the BST pin and the SW pin.
