Cxle8688 is a PFM Synchronous Boost DC / DC converter with high efficiency, low power consumption and low ripple

Cxle8688 is a PFM Synchronous Boost DC / DC converter with high efficiency, low power consumption and low ripple. The cxle8688 only needs three peripheral components to transform and boost the low input battery voltage to the required working voltage. The output voltage of cxle8688 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 cxle8688 system has the characteristics of low ripple and low noise.
The built-in synchronous switch tube of cxle8688 can greatly reduce the loss on the switch tube, making the efficiency up to 94%. Working in PFM mode, cxle8688 can effectively reduce the loss under light load mode and improve the service cycle of the equipment. At the same time, the low static current of the chip can further reduce the system loss.
