MP20073 – 2A, 1.3V-6.0V INPUT, DDR MEMORY TERMINATION REGUALTOR
MPS Proprietary Information. Unauthorized Photocopy and Duplication Prohibited.
Description
Power input for VTT regulator. Connect to GND through 10uF ceramic capacitor.
It is normally connected to the VDDQ of DDR memory rail.
Power output for the VTT LDO.
The exposed pad and GND pin must be connected to the same ground plane.
Kelvin sensed feedback signal.
Chip bias Voltage.
VTT regulator enable input. High to enable the chip.
Buffered output for the system. The receiving end of the DDR memory cells needs
this signal for their input comparator.
LDO signal input for generating VDDQ/2 reference.
