XL7036 Datasheet | XLSEMI

Features - Operation Voltage from 12V to 90V - Maximum Duty Cycle up to 100% - Minimum Drop Out 0.5V - Adjust VOUT from 1.25V to 20V - Max. IOUT=2.1A at VOUT=5V - Max. IOUT=1A at VOUT=12V or 15V - Max. output power less than 15W - Fixed 150KHz Switching Frequency - Internal Optimize HV Power MOSFET - High efficiency up to 90% - Excellent line and load regulation - Built in output short Protection Function - Built in current limit function - TO220-7L package General Description The XL7036 is a 150KHz 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 100%. Applications - Ebike Controller Power Supply - Tele / Networking Equipment Figure1. Package Type of XL7036 Rev 1.0 .xlsemi. 1 2.1A 150KHz 100V Buck DC to DC Converter Pin Configurations Datasheet XL7036 Figure2. Pin Configuration of XL7036 (Top View) Table 1 Pin Description Pin Number Pin Name FB VREG SW VC VIN OGND GND Description Feedback Pin (FB). Through an external resistor divider network, Feedback senses the output voltage and regulates it. The feedback threshold voltage is 1.25V. Supply Voltage Input Pin. A 10 µF ceramic decoupling capacitor is required. An external voltage between 7V and 9V can be applied to this pin to reduce internal power dissipation. Power Switch Output Pin (SW). Output is the switch node that supplies power to the output. Internal Voltage Regulator Bypass Capacity. In typical system application, The VC pin connect a 1u F capacitor to VIN. Supply Voltage Input Pin. XL7036 operates from 12V to 90V DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input. Output Ground Pin. Ground Pin.
