2.1A 100KHz 100V Buck DC to DC Converter Features - Operating Voltage: 8V~80V - Maximum Duty Cycle up to 85% - Minimum Drop Out 2.0V - Adjust VOUT from 1.25V to 20V - Max. IOUT=2.1A at VOUT=5V - Max. IOUT=1.2A at VOUT=15V - Fixed 100KHz Switching Frequency - Max. Output power less than 20W - Internal Optimize HV Power MOSFET - High efficiency up to 93% - Excellent line and load regulation - Built in current limit function - Built in output short Protection Function - TO263-7L package General Description The XL7056 is a 100KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 2.1A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external ponents, the regulator is simple to use and include internal frequency pensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 85%. Applications - Ebike Controller Power Supply - Tele / Networking Equipment Rev 1.9 Figure1.
