Description:Support is limited to customers who have already adopted these products.The ISL6260C is a multiple phase PWM buck regulator for microprocessor core power supply. The multiple phase implementation results in better system performance, superior thermal management, lower component cost, reduced power dissipation, and smaller implementation area. The ISL6260C multiphase controller together with ISL6208 external gate drivers provide a complete solution to power Intel's mobile microprocessors. The PWM modulator o
The recommended PCB layout for optimal performance involves keeping the power traces short and wide, using a solid ground plane, and placing the input and output capacitors close to the IC. Additionally, it's recommended to use a separate power plane for the high-current paths and to minimize the loop area of the current sense lines.
To select the right inductor for your design, consider the maximum current rating, inductance value, and DC resistance. The inductor should be able to handle the maximum output current of the converter, and the inductance value should be chosen based on the switching frequency and output voltage. The DC resistance should be low to minimize power losses.
The maximum junction temperature that the ISL6260CCRZ can handle is 150°C. However, it's recommended to keep the junction temperature below 125°C for optimal reliability and performance.
To troubleshoot issues with the converter not turning on, check the input voltage, enable pin, and power-good signal. Ensure that the input voltage is within the recommended range, the enable pin is properly biased, and the power-good signal is not asserting a fault condition. Also, check for any short circuits or open circuits on the PCB.
Yes, the ISL6260CCRZ is rated for operation up to 105°C ambient temperature. However, the IC's performance and reliability may degrade at high temperatures, so it's recommended to derate the output current and ensure proper thermal management.
