Product Details:

The XL6009 regulator is a wide input range,current mode, DC/DC converter which is capable of generating either positive or negative output voltages. It can be configured as either a boost, flyback, SEPIC or inverting converter. The XL6009 built in N-channel power MOSFET and fixed frequency oscillator, current-mode architecture results in stable operation over a wide range of supply and output voltages.The XL6009 regulator is special design for portable electronic equipment applications.

Need a boost? Using the XL6009 switching boost regulator IC this module can take an input voltage of between 5 and 32V DC and convert it to between 4 and 38V DC.

When using these modules remember that the output current will be a lot less than the input current, (remember - W = VA). For example, if you have a 10V output at 1A from a 5V input, the input current will be around 3.6A. The real-life maximum amount of power you can get out of these things is around 10W. 

To be honest these modules should be used when you don't have any other option, or if you only need a higher voltage at a low current. Otherwise it would be prudent to re-consider the power needs of your project.

This product is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module,capable of driving a 0-5A (Max) Adjustable load with high efficiency,
low ripple and excellent line and load regulation. Use as a step-down modules with overcurrent protection capabilities

The DC/DC buck module has applications where the input voltage is higher than the output voltage , such as battery, power transformer, DIY adjustable regulated power supply, LCD Monitor and LCD TVportable instrument power supply telecom/networking equipment,24V vehicle notebook power supply,industrial equipment buck. 12V buck to 3.3V, 12V buck to 5V, 24V buck to 5V,24V buck to 12V, 36V buck to 24V etc.


Applications:

• Use as a step-down modules with overcurrent protection capabilities

Usage:

• Adjust the voltage potentiometerso that the output voltage reaches the value you want.
• Use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the current potentiometer so that the output current reaches a predetermined overcurrent protection value. (For example, the meter displays the current value of 4A, then you can use the module to a maximum current of 4A)
• Connect the load.

 

Use as a battery charger

Usage:

• Make sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh, then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA)
• Under no-load conditions, adjust the Voltage potentiometer so that the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V)
• Use a multimeter to measure the output short-circuit current, while regulating the current potentiometer so that the output current reaches a predetermined Charging current value.
• Factory default is 0.1 times the charging current; (during charging,current is gradually reduced, if the charge current setting is 1A, then when the charge current is less than 0.1A, blue lights turned off, the green light is on, which means that the battery is fully charged)
• Connected to the battery charge. (1,2,3,4 steps as: Output is unloaded, do not connect the battery)

 

3.Use as a LED constant current driver module

Usage:

• Adjust the voltage potentiometer so that the output voltage reaches the value you want.
• Use a multimeter to measure the output short-circuit current, while regulating the current potentiometer so that the output current reaches a predetermined LED operating current.
• Connect LED, work. (1,2 steps as: Output is unloaded, do not connect LED)

Product Details:

DC-DC Step-down Adjustable Constant Voltage Module can be used to get adjustable output voltage ranges. The module provides a wide range of current output up to 12 A. With the heat sink mounted it can easily manage to run high power applications continuously (provided that for continuous high power output you need to use a cooling fan on the heat sink)
The Module is made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20°C to 100°C constant current 1A, temperature drift less than 1%); and therefore it is particularly most suitable for LED driver applications. The output current of the module can be raised up to 10A(for continuous use it is recommended up to 8A with an additional cooling fan)
To enhance the stabilization in output voltage has four high-frequency capacitance which gives the lower output ripple. Double heat sink design provides easy and fast heat dissipation. MOS Schottky diode independent heat sink, which heat dissipation is good, and won’t affect each other. Also using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
The module has onboard 3296 multiturn potentiometers for high accuracy voltage and current regulation to provide good stability. As voltage and current are adjustable, it gives very easy to use at multiple Application such as battery charging, LED Driver power supply, Vehicle Power Supply, etc which makes the module Multipurposeand hence this module is always in demand from our maker because of its wide range of application and low cost.
