Rev 0.1 DIO6305B High-Efficiency 1.2MHz, 1.1A Synchronous Step-Up Converter Features Descriptions High-Efficiency Synchronous-Mode The DIO6305B is a high efficiency boost regulator 2.7-5.25V input voltage range targeted for general step-up applications. It can Device Quiescent Current: 30A (TYP) be used for generating 5V at 600mA from a 3.3V Less than 1A Shutdown Current with 5V or rail or a Li-ion battery. 0V output voltage High switching frequency minimizes the sizes of Output Voltage Clamping: 6V inductor and capacitor. Integrated power Adjustable Output Voltage Up to 5.25V MOSFETs and internal compensation make the Power-Save Mode for Improved Efficiency at DIO6305B simple to use and fit the total solution Low Output Power into a compact space. Load Disconnect During Shutdown For light load current, the DIO6305B enters into 1.8V Logic on EN Pin for Control the power-save mode to maintain high efficiency. Thermal shutdown Anti-ringing control circuitry reduces EMI Green package: SOT23-6 is pin compatible. concerns by damping the inductor in -40C to +85C Operating Temperature Range discontinuous mode. The DIO6305B provides true output disconnect and this allows V to go to OUT zero volts during shutdown without drawing any current from the input source. The DIO6305B supports 1.8V logic for control. The output voltage of DIO6305B can be programmed by an external resistor divider.
