Which is the switching pin of the xl6009 IC?
The metal tab is internally connected with the Switching pin of the XL6009 driver ic. The pin description is also given in the above table. The important technical specifications of XL6009 IC is given below The above specification chart is showing that the minimum input voltage of this driver IC is 5V and the maximum is 32 Volt.
Is the xl6009 DC DC boost converter adjustable?
This DC-DC switching boost converter is capable of driving a 4A load with excellent line and load regulation. The main switching component XL6009 IC is available in fixed output voltages of 3.3 V, 5V, 12V, and an adjustable output version.
Is the xl6009 DC-DC Step Up module heat sink?
The XL6009-Adj based DC-DC step-up module offers 4A of rated current from a 3 – 32V of the input voltage. The power module has a potentiometer to adjust the output voltage according to the user needs. Although the module uses a PCB based heat sink it is recommended to use an additional heat sink if the output power rating exceeds 15W.
Which is xl6009 regulator is special design for portable electronic equipment?
The XL6009 regulator is special design for portable electronic equipment applications. T0263-5L Figurel. Package Type of XL6009 www.kylinchip.com þ@nçhip KylinChip Electronic (Shanghai) Co. Ltd XL6009 400KHz60V4ASwitching Current Boost / Buck-Boost/ Inverting DC/ DCConverter Pin Configurations T0263-5L VIN GND Metal Tab SW Figure2.
What kind of IC to use for buck boost?
There are many ways to build a buck-boost circuit, for the sake of this tutorial, we will be using the famous XL6009 DC/DC Converter IC. We have selected this IC because of its ease of availability and beginner-friendly nature.
How is the output of a boost converter limited?
The switching MOSFET of the boost converter is always the weak point, as I learned from cold, hard experience. The maximum output voltage of the boost converter is not limited by design but by the breakdown voltage of the MOSFET. 3. The inductor. Obviously, just any old inductor won’t work.
What kind of resistor is used in xl6009?
R1 is a variable resistor which is used for setting the output voltage. The R1 and R2 form a voltage divider that provides feedback to the driver IC XL6009. 10uH inductor L4 and 100uF capacitor C3 are used as an LC filter. Other than the Inductor, all the components should be available easily.
How to interface a switch to a pin?
To interface a switch we connect it to a pin (e.g., Figure 8.3) and initialize the pin as an input. The initialization function will enable the clock, set the direction register to input, turn off the alternative function, and enable the pin. Notice the software is friendly because it just affects PA5 without affecting the other bits in Port A.
Why is the xl6009 not a good regulator?
This is due to the high DCR value of inductors and the unavailability of the heat sink in the XL6009. Adequate heat sink and proper components can be useful for stable output. Overall, the circuit is working quite operational and performance is satisfactory.
