DC-DC átalakító kimenet Step Up Boost tápegység modul 3V–5V 1A USB töltő telefonhoz MP3 MP4 96% -os hatékonyság
DC-DC Converter Output Step Up Boost Power Supply Module 3V to 5V 1A USB Charger For Phone MP3 MP4 96% Efficiency
Output current expanded to rated 1A, can output 1.5A, using 2A Schottky diode, allowance recharge. For high current output, the input must provide sufficient current. With the new design scheme, the circuit design does not need electrolytic capacitor and tantalum capacitor (electrolytic capacitor has short life, tantalum capacitor has the danger of explosion). Three ceramic capacitors (MCC) are used.
 
The ripple is very low, only tens of millivolts.
 
4: also with the load indicator light and undervoltage indicator (when the battery voltage is less than 2.7V, the indicator light will be off with the load, when the battery voltage is greater than 2.7V, the indicator light will be on with the load, no load when the indicator light is light)
 
5: Ultra-small size, 30(L)*18(W)*9(H) mm (including USB connector)
 
6: high circuit conversion efficiency, high efficiency of more than 90% , in a single lithium battery efficiency is greater than 80% .
 
7: input low power reverse connection protection, if your battery with 2A protection plate when you input power positive and negative polarity reverse connection, the protection plate will protect, note that when there is no protection plate or the input current is greater than 2A, the input reverse connection protection will fail, will lead to module damage, remember.
 
8: low static current, static current will be less than 100 microamps. Connect to the battery without adding a switch.
