PRODUCTION DATA.
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. |
