The PM6670AS is a complete DDR2/3 power supply regulator designed to meet JEDEC specifications. It integrates a constant on-time (COT) buck controller, a 2 Apk sink/source low drop out regulator and a 15 mA low noise buffered reference. The COT architecture assures fast transient response supporting both electrolytic and ceramic output capacitors. An embedded integrator control loop compensates the DC voltage error due to the output ripple. The 2 Apk sink/source linear regulator provides a low dropout voltage of 0.35V and a high output current of 2A.
