LM2596 Adjustable Constant Current Voltage Board DC-DC Power Supply Module LED Driver Battery Charger
Feature:
1. The module uses high-quality LM2596 chips made in China, with high efficiency (up to 92%) and low calorific value. It can easily reach over 3A current.
2. At the same time, it can control output current with the operation of original TI, so that the overall output is very stable.
3. This module uses a low ESR original for Sanyo filter capacitor, which can make the ripple voltage as low as 50 mV.
4. This module uses machine patch and reflow welding. At the same time, each module undergoes two hours of aging test before shipment to ensure high reliability.
Specification:
Input voltage: 7V-35V
Output voltage: 1.25V-30V
Output current: adjustable maximum 3A
Conversion efficiency: 92% (highest)
Switching frequency: 150 KHz
Output ripple: 50mV (maximum) 20M bandwidth
Load adjustment rate: ±0.5%
Voltage adjustment rate: ±2.5%
Operating temperature: -40℃-85℃
Product size: 48mm*23mm*14mm/1.88*0.9*0.55''
Packing weight: 15g
Battery charging method:
1. Determine the floating charging voltage and charging current of the rechargeable battery and the input voltage of the module.
2. Adjust the constant voltage potentiometer and adjust the output voltage to about 5V.
3. The output short circuit current is measured with the current barrier of multimeter 10A, and the output current reaches the predetermined charging current value by adjusting the constant current potentiometer.
4. Charging current is 0.1 times as much as charging current (constant current value) by default. If you need to adjust, please adjust the switch current potentiometer; (generally not adjusted).
5. Adjust the constant voltage potentiometer to make the output voltage reach the floating charge voltage.
6. Connect the battery and charge it. (Steps 1, 2, 3, 4, 5 are module input power supply, output no-load battery.)
LED constant current drive method:
1. Make sure you need to drive the working current and the maximum working voltage of the LED.
2. Adjust the constant voltage potentiometer and adjust the output voltage to about 5V.
3.  The output short circuit current is measured with the current barrier of multimeter 10A, and the output current reaches the predetermined charging current value by adjusting the constant current potentiometer.
4. Adjust the constant voltage potentiometer to make the output voltage reach the maximum working voltage of the LED.
5. Connect the LED and test it.
Note:
Please allow 1-3mm differs due to manual measurement.
Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
