      CXDC65166-30PB CXDC65166-33PB CXDC65166-36PB CXDC65166-50PB integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of the output voltage.CXDC65166-30PB CXDC65166-33PB CXDC65166-36PB CXDC65166-50PB is available in SOT-89-3、SOT-23-3 and SOT-23-5 packages which is PB free. And in 5-pin packages, such as SOT-23-5, the device can be switch on or off easily by CE pin, to minimize the standby supply current 

The CXDC65166-30PB CXDC65166-33PB CXDC65166-36PB CXDC65166-50PB series are CMOS-based PFM step-up DC-DC Converter. The converter can start up by supply voltage as low as 0.8V, and capable of delivering maximum 200mA output current at 3.3V output with 1.8V input Voltage.Quiescent current drawn from power source is as low as 7uA. All of these features make CXDC65166-30PB CXDC65166-33PB CXDC65166-36PB CXDC65166-50PB series be suitable for the portable devices, which are supplied by a single battery to four-cell batteries.
To reduce the noise caused by the switch regulator, CXDC65166-30PB CXDC65166-33PB CXDC65166-36PB CXDC65166-50PB is well considerated in circuit design and manufacture, so that the interferer to other circuits by the device is reduced greatly.
