Features - Operation Voltage：5V~72V - Minimum Drop Out：1.5V - Feedback Voltage Accuracy ±2% - Fixed 120KHz Switching Frequency - 0.6A Constant Output Current Capability - Internal Optimize Power MOSFET - High efficiency up to 93% - Max. Output power up to 5W - Excellent line and load regulation - Built in thermal shutdown function - Built in current limit protection function - Built in output short protection function - Device HBM ESD Classification Level Class3B - Available in SOP8 package General Description The XL9711 is a 120KHz fixed frequency PWM synchronous buck DC/DC converter, capable of driving a 0.6A load with high voltage, high efficiency, low ripple and excellent line and load regulation. XL9711 supports wide input operating voltage range of 5V~72V and a maximum duty cycle of 90% output. A built-in loop pensation module reduces ponents in the system, lowering power system cost and reducing printed circuit board space. The XL9711 has built-in thermal shutdown, current limit protection and output short protection function and so on. When the output short protection function happens, the operation frequency will be reduced about from 120KHz to 30KHz.
