Pin Configuration of XL7036 (Top View) Table 1 Pin Description Pin Number Pin Name 1 FB 2 VREG 3 SW 4 VC 5 VIN 6 OGND 7 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 1uF 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. 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 XL7036. The exposed PAD is GND. Rev 1.0 www.xlsemi.com 2 Datasheet 2.1A 150KHz 100V Buck DC to DC Converter XL7036 Function Block Figure3.
