The APW7026 Provides the power control and protection for three output voltages in VGA Card applications. It integrates two PWM controllers, one linear controller as well as the monitoring and protection functions into a single package. One PWM controller (PWM1) regulates the termination voltage VTT(1.25V) with a synchronous-rectified buck converter. The second PWM controller (PWM2) supplies the Core power NVVDD ( 2.05V ) with a standard buck converter . The linear controller regulates 2.5V power for FBVDDQ.
