Automotive Single-Phase Core Regulator for IMVP-6 ?
CPUs
ISL78211
The ISL78211 is a single-phase buck regulator implementing
lntel? IMVP-6? protocol, with embedded gate drivers. lntel?
Mobile Voltage Positioning (IMVP) is a smart voltage regulation
technology effectively reducing power dissipation in lntel?
Pentium processors.
The heart of the ISL78211 is the patented R 3 Technology?,
Intersil’s Robust Ripple Regulator modulator. Compared with the
traditional multi-phase buck regulator, the R 3 Technology? has
faster transient response. This is due to the R 3 modulator
commanding variable switching frequency during a load
transient.
The ISL78211 provides three operation modes: the Continuous
Conduction Mode (CCM), the Diode Emulation Mode (DEM) and
the Enhanced Diode Emulation Mode (EDEM). To boost battery
life, the ISL78211 changes its operation mode based on CPU
mode signals DPRSLRVR and DPRSTP#, and the FDE pin setting,
to maximize the efficiency. In CPU active mode, the ISL78211
commands the CCM operation. When the CPU enters deeper
sleep mode, the ISL78211 enables the DEM to maximize the
efficiency at light load. Asserting the FDE pin of the ISL78211 in
CPU deeper sleep mode will enable the EDEM to further decrease
the switching frequency at light load and increase the regulator
efficiency.
A 7-bit Digital-to-Analog Converter (DAC) allows dynamic
adjustment of the core output voltage from 0.300V to 1.500V.
The ISL78211 has 0.8% system voltage accuracy over entire
temperature.
A unity-gain differential amplifier provides remote voltage
sensing at the CPU die. This allows the voltage on the CPU die to
be accurately measured and regulated per lntel? IMVP-6
specification. Current sensing can be implemented through
either lossless inductor DCR sensing or precise resistor sensing.
If DCR sensing is used, an NTC thermistor network will thermally
compensates the gain and the time constant variations caused
by the inductor DCR change.
The ISL78211 provides the power monitor function through the
PMON pin. PMON output is a high-bandwidth analog voltage
signal representing the CPU instantaneous power. The power
monitor function can be used by the system to optimize the
overall power consumption, extending battery run time.
The ISL78211 is tested to AEC-Q100 specifications.
