Rev 1.2 DIO6023 High-Efficiency 1MHz, 2.5A continuous, 3A Peak, Synchronous Step Down Converter Features Descriptions Low R for internal switches (top/bottom) The DIO6023 is a high-efficiency 1MHz DS(ON) 100m/70m, 3A synchronous step-down DC-DC regulator IC 2.7-5.5V input voltage range capable of delivering up to 3A output current. 1MHz switching frequency minimizes the external components The DIO6023 operates over a wide input voltage Internal soft start limits the inrush current ranging from 2.7V to 5.5V and integrate main 100% dropout operation switch and synchronous switch with very low RoHS Compliant and Halogen Free R to minimize the conduction loss. Low DS(ON) Compact and thermally enhanced SOT23-6 output voltage ripple and small external inductor and capacitor sizes are achieved with 1MHz switching frequency.

Pull high to turn on. Do not float. EN GND Ground Inductor pin. Connect this pin to the switching node of inductor. LX IN Power Input Power good indicator. When the output voltage exceeds 90% of regulation point, PG it becomes open drain low otherwise. Output Feedback Pin. Connect this pin to the center point of the output resistor divider FB (as shown in Figure 1) to program the output voltage: Vout=0.6*(1+R1/R2). www.dioo.com 2018 DIOO MICROCIRCUITS CO., LTD DIO6023 Rev. 1.2
