Applications Note: AN_SY8009 High Efficiency 1.5MHz, 1MHz, 1.5A, 2A Synchronous Step Down Regulator Preliminary Spec General Description The SY8009A and SY8009B are high-efficiency , high frequency synchronous step-down DC-DC regulator ICs capable of delivering up to 1.5A, 2A output currents. The SY8009 family operate over a wide input voltage range from 3V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. Low output voltage ripple an
