Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. Wide 10V to 70V Input Voltage Range Output Adjustable from 1.25V to 50V Maximum Duty Cycle 100% Minimum Drop Out 0.3V Fixed 180KHz Switching Frequency Maximum 1.2A Switching Current Internal Optimize Power MOSFET Recommend output power less than 10W High efficiency Excellent line and load regulation Built in thermal shutdown function Built in current limit function Built in output short protection function Available in SOP8L package The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An over current protection function is built inside. When short protection function happens, the operation frequency will be reduced from 180KHz to 36KHz. An internal compensation block is built in to minimize external component count.

Pin Configuration of XL7007 (Top View) Table 1 Pin Description Pin Number 1 Pin Name NC 2 FB 3 VC 4 VIN 5,6 SW 7,8 GND Rev 1.0 Description No connected, hold floating; Feedback Pin (FB). Through an external resistor divider network, FB senses the output voltage and regulates it. The feedback threshold voltage is 1.25V. Internal Voltage Regulator Bypass Capacity. In typical system application, The VC pin connect a 1uf capacity to VIN. Supply Voltage Input Pin. XL7007 operates from a 10V to 70V DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input. Power Switch Output Pin (SW). SW is the switch node that supplies power to the output. Ground Pin. Care must be taken in layout. This pin should be placed outside of the Schottky Diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into XL7007. 深圳市龙华新区油松路天汇大厦Ｃ栋２０５ 2 www.jinrui-tech.com 深圳市劲锐科技有限公司 SHENZHEN JINRUI TECHNOLOGIES CO., LTD.
