The PM6670S is a complete DDR2/3 power supply regulator designed for portable applications to meet JEDEC specifications. It integrates a constant on-time (COT) buck controller, a 2 Apk sink/source low dropout regulator (LDO), and a 15 mA low noise buffered reference. The COT architecture ensures a fast transient response supporting both polymeric and ceramic output capacitors. An embedded integrator control loop compensates the DC voltage error caused by the output ripple. The 2 Apk sink/source linear regulator provides the memory termination voltage with a fast load transient response. The device is fully compliant with system sleep states S3, S4, and S5, setting the LDO output to high-impedance in the suspend-to-RAM state, and performing the tracking discharge of all outputs in the suspend-to-disk state.
