Cxsu6333 is a constant peak current mode asynchronous PWM boost converter. An external Schottky diode is required. In light load, the cxsu6333 works in light load mode. The static current is 100 Au and the turn off current is less than 1 AU. The on resistance of internal NMOS is 200m Ω, which ensures high efficiency in the whole output load range. 2A peak current causes acxsu6333 to provide 1A output load current. Very suitable for mid and mobile power supply. The input voltage range is 3V ~ 25V. Internal working frequency is set at 1.0mhz
