???5A Input LM2587 DC-DC Step Up Boost Module Adjustable Power Supply
Feature:
This module uses LM2587 chip， instantaneous input current can be up to 5A， high efficiency (up to 92%)， small heat value， under no radiator can up to 15W， add the radiator can go to 20W output power.
This module uses the original Sanyo low ESR filter capacitor， meanwhile， in order to make more small output ripple， specially add a LC filter circuit at the output port that can make ripple voltage as low as 50mV (in the case of output voltage is 24V， 12V to 20mV below)， suitable for most occasions.
This module uses machine placement， reflow soldering.

Applications:
DIY a mobile power， only need to connect lithium battery-powered in input， it can output 4-35V voltage for your cell phone， MP3， MP4， PSP and many other devices charging， very simple and convenient.
Boost charger， you can charge your 4-35V device with 2*AA batteries or lithium batteries.
Power for your electronic devices when you need 4-35V powered equipment， but you are only has lithium battery-powered， with this module can boost to 4-35V， solve your problems.
Pre-supply system， when you do a project， the input supply voltage lower than the voltage you need (4-35V)， this module will be your best choice， do not need debug， can directly hands-on the machine to work， easier to do efficient large power boost.
Note:
This module is an adjustable boost module， can be adjusted the blue adjustable resistor to change the output voltage， the highest output voltage is 35V.
Module indicated IN - (negative input)， IN + (positive input)， OUT - (negative output)， OUT + (positive output)， please note must be correct connected， otherwise may cause damage to the module.
Do not exceed the rated output power of the module， for example this module (20W) can not be used to supply laptop (90W) to use.
The module has no short circuit protection， if output short circuit， the system will lock the output to 0， excluding short-circuit， re-power to re-output.
Package included:
1 x LM2587 DC-DC Boost Module
