XL6009400KHz 60V 4A Switching Current Boost / Buck-Boost / Inverting DC/DC ConverterPin Configurations Figure2. Pin Configuration of XL6009 (Top View) Table 1 Pin Description Pin NumberPin NameDescription 1 GND Ground Pin. Enable Pin. Drive EN pin low to turn off the device, drive it 2 EN high to turn it on. Floating is default high. 3 SW Power Switch Output Pin (SW). Supply Voltage Input Pin. XL6009 operates from a 5V to 32V 4 VIN DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input. Feedback Pin (FB). Through an external resistor divider 5 FB network, FB senses the output voltage and regulates it. The feedback threshold voltage is 1.25V. Rev 1.1 www.xlsemi.com 2
