   产品概述 返回TOPDu0嘉泰姆

   CXSU63221 CXSU63222 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 100mA output current at 3.3V output with 1.8V input Voltage. Quiescent current drawn from power source is as low as 10uA. All of these features make CXSU63221 CXSU63222 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, CXSU63221 CXSU63222 is well considerate in circuit design and manufacture. So that the interferer to other circuits by the device is reduced greatly. CXSU63221 CXSU63222 integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of the output voltage. TCXSU63221 CXSU63222is available in TO92 SOT-89-3 and SOT-23-3 packages that 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.
