Product Description


Highest Efficiency 96% 1A DC-DC Step-UP Power Supply Boost Voltage Converter Regulator module Booster Circuit Board 3V to 5V

1: The original US imported chips, and expansion flow MOS, definitely not homemade chips.


2: extend to the rated output current is 1A, the maximum can be output 1.5A, 2A Schottky diode using the balance recharge.


3: A new program design, circuit design does not require electrolytic and tantalum capacitors (electrolytic capacitor life is short, there is a risk of explosion tantalum capacitors) Now used on circuits with high-end ceramic capacitor (MCC) 3 stars..


Ripple is very low, only a few tens of millivolts, many colleagues have reached a 500 mV ripple great, the equipment will cause an invisible injury, serious work will lead to abnormal or damaged equipment.


4: The same with a load indicator and voltage indication (when the battery voltage is less than 2.7V with a load indicator in the case will go out when the battery voltage is greater than 2.7V with a load when the indicator light, without a load when the light micro- Liang)


5: Ultra -small size, 14.1 * 18.8 * 5.5 mm


6: Circuit conversion efficiency, high efficiency over 90% of the time, the efficiency of a single lithium battery is also greater than 80% minimum, unlike some peers efficiency is only 60-70% efficiency.


7: Enter the low-power reverse polarity protection, if you battery protection board with a 2A input power when you reversed polarity, the protection board will protect, pay attention when there is no protection board or the input current is greater than 2A, input reverse polarity protection will fail, cause damage to the module, remember.


8: Ultra-Low Quiescent Current, the new version, the quiescent current to less than 100 microamps Connected to the battery without adding switches..



With voltage indicator (input voltage is below 2.7V LED light off)

1). DIY a mobile power, only need to enter the battery connected to a power supply, you can output 5V voltage for your phone, MP3, MP4, PSP charger, very simple and convenient, oh.


2) In order to power your electronic devices when your device needs 5V power supply often, however you are now in the hands only lithium battery -powered, with our direct boost to this module 5V, solve your problems.


3) The system level power supply before, when you do a project, when the input is battery powered (1-5V), when, and your system board and requires a 5V regulated power supply, then you choose this module we will be your most good choice, do not debug directly on the machine can work, easy to do and efficient high-power boost.
