Cxsu6392 is a true off Synchronous Boost Converter with output up to 5V / 3a and boost up to 5V / 2A efficiency up to 90% under 3.3V input. The cxsu6392 adopts 1MHz oscillation frequency and 2.2uh inductance. Only two 22uF output capacitors are needed to achieve 50mV output ripple. Under the condition of such high current, high efficiency and high stability output, and with the design of extremely high power density, the packaging situation of qfn3x3-16 is adopted. At the same time, the cxsu6392 integrates the USB interface automatic identification function that can be compatible with the high current charging of apple and Samsung tablet computers. It is especially suitable for the electronic system with high-capacity lithium battery, such as MiFi, mini PCI-E module, mobile power supply, high-power Bluetooth speaker, which needs to output high-power 5V voltage.
