ISL6211 is the core central processor of a single -output power controller Transmeta Crusso. ISL6211 includes a 5 -digit modular converter (DAC), which is used to adjust the multi -voltage output voltage from 0.6 volts to 1.75 volt DC power. The settings may be changed during the operation of the association. Special measures have been taken to allow this transitional rotation rate to meet the long -term operation requirements of Transmeta with controlling the condition of control # 8482 ; technology. Accurate reference and proprietary integrated compensation architecture provides excellent static and dynamic iron core voltage regulation. In the rated current, the controller is 300kHz or 600kHz at the optional frequency. When the filter inductance current becomes discontinuous, the controller has significantly improved the system efficiency in the stagnation mode. The stagnation running mode can be sold at the specified control. ISL6211 monitor output voltage. Powerful products should be completed and output in supervision. Built -in overvoltage protection can prevent loads with output voltage higher than 1.9V. When the output is lower than the set value of 75%. Pulse width modulation controller's over -current circuit monitoring converter load passes through a lower MOSFET voltage drop by induction. This over -current threshold is set by an external resistor. If you need precision over current protection, you can choose to use a current -influenza resistor on the outside.
