GENERAL DESCRIPTION
The ASP08001
is an integrated power control IC with a PMBus
interface. The ASP0800 is a highly efficient, multiphase,
synchronous buck switching regulator controller, which aids
design of High Efficiency and High Density solutions.
The PMBus interface enables digital programming of key
system parameters to optimize system performance and provide
feedback to the system. The ASP0800 is compatible for use with
coupled inductors,
The ASP0800 is optimized for converting a 12 V main supply
into the core supply voltage required by high performance Intel
processors. It uses an internal 8-bit DAC to read the voltage
identification (VID) code directly from the processor, which is
used to set the output voltage between 0.375 V and 1.6 V.
This device uses a multimode PWM architecture to drive the
logic-level outputs at a programmable switching frequency that
can be optimized for VR size and efficiency. The ASP0800 can
be programmed for 1-, 2-, 3-, 4-, 5-, 6, 7 or 8- phase operation,
allowing for the construction of up to 8 complementary buck
