The LM2577S/LM2596 DC 4-35V to 1.25-25V automatic buck-boost converter, max output current 3A, output power 5W, automatic buck-regulator circuit, applicable high power led driver, solar panels.

Feature:

Module Properties: non-isolated Boost Buck constant current, constant voltage module (CC CV) charging module
Scope:
High-power constant current LED driver.
Battery charger (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charger, solar panels, wind generators.
Solar Panel, Wind generator voltage regulator, Car Power Supply.
Input voltage: 4-35V
Output voltage: 1.25-25V
Output Current: Rate 3A, Max 4A ( If more than 15W, please install the heat sink, this item do not include heat sink)
Constant current range :0-2A (adjustable)
Revolving light current: constant current value * (1% -100%), Revolving light current value Linkage with the constant current value, such as the constant current value is 3A, Revolving light current is set to constant current of 0.1 times (0.1 * 3A = 0.3A) when adjusted to the constant current value when the 2A, then Revolving light current is 0.2A (0.1 * 2A = 0.2A). Default 0.1 times
Minimum voltage pressure: 2V
Output power: natural cooling 15W, (if install heat sink can be 25W)
Conversion efficiency: 80% (the higher the output voltage, the higher the efficiency
Operating Temperature: Industrial (-40°c to +85°c) (if ambient temperature exceeds 40 °c, please lower power use, or to enhance heat dissipation)
Full load temperature rise: 45°c
This Converter only can rise Voltage, it can not rise Power.
if use Solar as power supply, please make sure the input power is 1.1 times than the output power.

Note:

Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
Indicator: constant current Indicator Red, Charging indicator Red, Full charge indicator Blue.
Output short circuit protection: Yes, constant current (constant current setting values)
Input Reverse Polarity Protection: None (Please Series diode at the input port.)
Connection: Welding, can be directly soldered to a PCB

Battery Charging method:

1. Make sure the recharge battery float voltage and charge current, input voltage of the module.
2. adjust constant voltage regulator, the output voltage about 3V.
3. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined charge current value;
4. Adjust Constant regulator allows Output voltage reaches the float voltage;
5. connected to the battery, try charging.
(1,2,3,4 step input connect power, output do not connect battery.)

LED constant current driver Usage:

1. Make sure LED current and the maximum operating voltage;
2. adjust constant voltage regulator, the output voltage about 3V.
3. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined LED working current value;
4. Adjust Constant regulator allows Output voltage Reach LED maximum working voltage;
5. Connected to the LED, test.
(1,2,3,4 take steps input connect power, output do not connected LED.)

Package Includes:

1x DC-DC Converter
