Rev 1.3 DIO6010 High-Efficiency 1.5MHz, 1A Continuous, 1.5A Peak Output Synchronous Step Down Converter Features Descriptions Low R for internal switches (top/bottom) The DIO6010 is high-efficiency, high frequency DS(ON) 230m/170m, 1.0A synchronous step-down DC-DC regulator ICs 2.5-5.5V input voltage range capable of delivering up to 1A continuous output 40A typical quiescent current currents. The DIO6010 family operate over a wide High light load efficiency input voltage range from 2.5V to 5.5V and High switching frequency 1.5MHz minimizes integrate main switch and synchronous switch the external components with very low RDS(ON) to minimize the conduction Internal soft start limits the inrush current loss. 100% dropout operation Green package: DFN2*2-6, SOT23-5 is pin Low output voltage ripple and small external compatible inductor and capacitor sizes are achieved with greater than 1.5MHz switching frequency.
