Intersil has developed a point-of-load power solution for use with the Spartan-6 FPGA SP623 and Virtex-6 FPGA ML623 evaluation kits from Xilinx Corp.
The POL supports all Multi-Gigabit Transceiver (MGT) power requirements and uses the Intersil ISL6442 triple output DC/DC controller
The evaluation kit also includes the Intersil ISL22317 digitally controlled potentiometer (DCP), which can dynamically change the output voltages as required.
The triple-output ISL6442 integrates complete control, monitoring and protection functions for two synchronous buck PWM controllers plus a linear regulator controller. Input voltage ripple and total RMS input current is reduced by synchronized 180 degree out-of-phase operation of the two PWMs.
