PM6670ASTR Description

Short technical summary and product information.

The STMicroelectronics PM6670ASTR is a specialized power management integrated circuit designed for DDR2 and DDR3 memory supplies. It meets JEDEC specifications and integrates a constant on-time (COT) buck controller along with a 2A sink/source low dropout regulator (LDO) and a 15mA low noise buffered reference.

 

The COT architecture ensures fast transient response, supporting both electrolytic and ceramic output capacitors. The device features a wide input voltage range of 4.5V to 36V. It offers fixed output voltages of 1.8V for DDR2 and 1.5V for DDR3, as well as an adjustable output voltage from 0.9V to 2.6V. The integrated VTT LDO provides the memory termination voltage with fast load transient response.

 

This controller is designed for applications such as DDR2/3 memory systems, digital TV systems, and SSTL/HSTL bus termination. It is compliant with system sleep states S3 and S4/S5, providing high impedance for the LDO output in Suspend-To-RAM and tracking discharge in Suspend-To-Disk.

 

The PM6670ASTR is available in a 24-VFQFPN (4x4) package and is designed for surface mounting. It operates within a temperature range of -40°C to 85°C.
