PM6670 Overview
The device PM6670 is a plete 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. architecture assures fast transient response supporting both electrolytic and ceramic output capacitors.
