Micro High Efficiency 2A High Efficiency Brisk DC/DC Voltage Regulator CXSU63289 Current Mode PWM Control Loop

CXSU63289 is a miniature, high efficiency, step-up DC/DC regulator. The circuit consists of current mode PWM control loop, error amplifier, ramp compensation circuit, comparator and power switch. The chip can work efficiently and stably in a wide load range, with a 4A power switch and soft start protection circuit. Up to 93% conversion efficiency can effectively extend battery life. The output voltage can be set by adjusting the two applied resistors.
