Description
The PM6652 is a single phase, step-down SMPS
controller with high precision 7 bit DAC. It has
been designed to supply the CPU and the
graphics core (render engine) of the Intel® mobile
platform, according with Intel MVP6.5
specifications.
The PM6652 can also be configured to supply the
7-bit family, VR11 compliant, ATOM® processors.
The controller, based on constant on-time (COT)
architecture, allows real-time dynamic switching
of the core operating voltages and frequencies,
working in both performance and suspend render
states.
An embedded integrator control loop
compensates the DC voltage error due to the
output ripple.
Applications
Intel mobile graphic core IMVP6.5
Intel mobile CPU IMVP6.5
Intel ATOM® VR11 based devices
Notebook, netbook and nettop computers
Handheld and PDAs
Table 1. Device summary
The high efficiency at light load, achieved with
pulse skipping working mode, and the extremely
low shutdown and quiescent adsorbed current,
make the PM6652 the ideal choice in battery
powered devices.
