Cxsu6330h is a constant peak current mode asynchronous PWM boost converter. An external Schottky diode is required. In light load, the cxsu6330h works in light load mode. The static current is 100au, and the turning off current is less than 1AU. The on resistance of internal NMOS tube is 130m Ω, which ensures high efficiency in the whole output load range. 3A peak current causes the cxsu6330h to provide 1.5A output load current. Very suitable for mid and mobile power supply. The input voltage range is 2.5V ~ 5.5V. Internal working frequency is set at 1.0mhz
