DIO6305BCST6

The DIO6305B is a high efficiency boost regulator targeted for general step-up applications. It can be used for generating 5V at 600mA from a 3.3V rail or a Li-ion battery. High switching frequency minimizes the sizes of inductor and capacitor. Integrated power MOSFETs and internal compensation make the DIO6305B simple to use and fit the total solution into a compact space. For light load current, the DIO6305B enters into the power-save mode to maintain high efficiency. Anti-ringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode. The DIO6305B provides true output disconnect and this allows VO(UT) to go to 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.
