product features:
? The module uses a high-quality LM2577 chip, which has high efficiency (92%) and low heat generation. It can reach 15W without a radiator, and can reach an output power of 25W with a radiator. This module uses
low ESR's original Sanyo filter capacitor can make the ripple voltage as low as 50mV, which is suitable for most occasions.


? This module uses machine patching and reflow soldering. At the same time, each module has undergone a two-hour aging test before shipment to ensure high reliability.
 
Application range
? DIY a mobile power supply, only need to connect a battery to the input, it can output 4-35V voltage to supply power for your mobile phone, MP3, MP4, PSP charging and many other devices, very simple and convenient.
? Boost charger, you can use 2 AA batteries or lithium batteries to charge your 4-35V devices.
? Power supply for your electronic equipment. When your equipment needs 4-35V power supply, but you only have a lithium-ion battery for power supply, our module can directly boost the voltage to 4-35V to solve your troubles.
? The power supply of the front stage of the system, when you are working on a certain project, when the input power supply voltage is lower than the voltage you need (4-35V), then you can choose our module, and you can work directly on the computer without debugging, easy to do to high-efficiency high-power boost.
