Manufacturer:INFINEON Description:Since power dissipation inside a microprocessor is proportional to the square of the core voltage, Intel XScale processors implement DVM as a means to more efficiently utilize battery capacity. To support this power saving architecture, the ISL6271A integrates an I2C bus for communication with the host processor. The processor, acting as the bus master, transmits a voltage level and voltage slew rate to the ISL6271A appropriate to the processing requirements; higher core voltages support higher operating frequencies and code execution. The bus is fully compliant with the Phillips® I2C protocol and supports both standard and fast data transmission modes. Alternatively, the output of the core regulator can be programmed in 50mV increments from 0.85V to 1.6V using the input Voltage ID (VID) pins. All three regulators share a common enable pin and are protected against overcurrent, over temperature and undervoltage conditions. When disabled via the enable pin, the ISL6271A enters a low power state that can be used to conserve battery life while maintaining the last programmed VID code and slew rate. An integrated soft-start circuit transitions the ISL6271A output voltages to their default values at a rate determined by an external soft-start capacitor. |
