Cxsu6335 series is a PFM controlled switch type DC / DC boost and voltage stabilizing chip, which is mainly composed of reference voltage reference, oscillator and comparator, with low output voltage ripple, high conversion efficiency and strong load capacity. The cxsu6335 requires only one inductor and one capacitor on the periphery. When the voltage at the cont point exceeds the limit value, the protection circuit will turn off the built-in FET to prevent device damage. Its protection characteristics, small package and low power consumption are very suitable for portable products
