Cxsu6307 is a miniature, high efficiency, boost DC / DC regulator. The circuit consists of current mode PWM control loop, error amplifier, bias compensation circuit, comparator and power switch. The chip can work efficiently and stably in a wide load range. Built in a 3A power switch. Lithium battery power supply can provide 1.2A output current. 80ua static current and 92% conversion efficiency can effectively prolong the battery life. The output voltage can be set by adjusting the two external resistances.
