PM6670 Datasheet (STMicroelectronics) - Complete DDR2/3 memory power supply controller

PM6670, Complete DDR2/3 memory power supply controller

The device PM6670 is a complete DDR2/3 power supply regulator designed to meet JEDEC specifications.

It integrates a Constant On-Time (C.O.T.) buck controller, a 2Apk sink/source Low Drop Out regulator and a 15mA low noise buffered reference.

The C.O.T.

architecture assures fast transient response s
