Two-Phase Core Regulator for IMVP-6 Mobile CPUs

The ISL6262 is a two-phase buck converter regulator implementing Intel® IMVP-6 protocol, with embedded gate drivers. The two-phase buck converter uses two interleaved channels to effectively double the output voltage ripple frequency and thereby reduce output voltage ripple amplitude with fewer components, lower component cost, reduced power dissipation, and smaller real estate area.The heart of the ISL6262 is R3 Technology™, Intersil’s Robust Ripple Regulator modulator. Compared with the traditional multiphase buck regulator, the R3 Technology™ has the fastest transient response. This is due to the R3modulator commanding variable switching frequency during a load transient.Intel Mobile Voltage Positioning (IMVP) is a smart voltage regulation technology, which effectively reduces power dissipation in Intel Pentium processors. To boost battery life, the ISL6262 supports DPRSLRVR (deeper sleep), DPRSTP# and PSI# functions and maximizes the efficiency via automatically enabling different phase operation modes. At heavy load operation of the active mode, the regulator commands the two phase continuous conduction mode (CCM) operation. While the PSI# is asserted at the medium load in the active mode, the ISL6262 smoothly disables one phase and operates in a one-phase CCM. When the CPU enters deeper sleep mode, the ISL6262 enables diode emulation to maximize the efficiency at the light load. A 7-bit digital-to-analog converter (DAC) allows dynamic adjustment of the core output voltage from 0.300V to 1.500V. A 0.5% system accuracy of the core output voltage over temperature is achieved by the ISL6262. A unity-gain differential amplifier is provided for remote CPU die sensing. This allows the voltage on the CPU die to be accurately measured and regulated per Intel IMVP-6 specifications. Current sensing can be realized using either lossless inductor DCR sensing or precision resistor sensing. A single NTC thermistor network thermally compensates the gain and the time constant of the DCR variations.
