The FAN5026 is a dual DDR / dual-output PWM controller that provides high efficiency and regulation for powering I/O, chip-sets, and memory banks in high-performance computers, set-top boxes, and VGA cards. It features DDR mode, two independent regulators, wide input range, and supports DDR-II and HSTL.
The FAN5026 is a highly flexible, dual synchronous switching PWM controller designed for generating Vppa and Vr voltages required to power I/O, chip-sets, and memory banks in high-performance computers, set-top boxes, and graphics cards. It supports various operating modes including DDR Mode with in-phase operation, 90° phase-shifted two-stage DDR mode, and dual independent regulators with 180° phase shift.
