5019MTC - Fairchild Semiconductor

5019MTC FAN5019MTC

The FAN5019 is a multi-phase DC-DC controller for implementing high-current, low-voltage, CPU core power regulation circuits. It is part of a chipset that includes external MOSFET drivers and power MOSFETS. The FAN5019 drives up to four synchronous-rectified buck channels in parallel. The multi-phase buck converter architecture uses interleaved switching to m.
