Cxsu63193 is a PFM Synchronous Boost DC / DC converter with high efficiency, low power consumption and low ripple. The cxsu63193 only needs three peripheral components to transform and boost the low input battery voltage to the required working voltage. The output voltage of cxsu63193 can be selected through internal regulation (step 0.1V), which is convenient for customers to apply to different output load situations. The output voltage of cxsu63193 system has the characteristics of low ripple and low noise. The built-in synchronous switch of cxsu63193 can greatly reduce the loss on the switch, making the efficiency up to 95%. Working in PFM mode, cxsu63193 can effectively reduce the loss under light load mode and improve the service life of the equipment. At the same time, the low static current of the chip can further reduce the system loss.
