LM2577S LM2596S Boost Buck Module

It is aLM2577S LM2596S Boost Buck Module 15W Adapter/Charging Module/Power Supply Module with Applications of DIY Power Adapter/Charger, industrial equipment; electronic equipment, Communications Equipment, Power Tools, Car Driving Recorder, Car GPS, Car audio, LCD TV; Advertising screen, Monitoring System, LED lights, Fan, intercom and monitor system, etc.

Features:

Module Properties: non-isolated Buck-Boost constant current, constant voltage module (CC-CV) charging module
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.
Output Current: Rate 3A, Max 4A ( If more than 15W, please install the heat sink, this item do not include heatsink)
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

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.
