ITEM NAME:DC-DC Step-up Converter 3V 3.7V 4.2V to 5V 3A 15W Power Supply Boost Module M&O The power supply module is the result of our careful design, the core components of all imported original. Using chip technology, DC-DC 3V L 5V boost circuit with USB output, wide scope of work, work from 3V-5V regulated output 5V / 3A circuit, to the mobile phone, a good way to MP3, MP4, PSP, mobile device charging! Working with sections 2 AA / AA batteries, you can phone MP3, MP4 charge. Coupled with a large-capacity lithium battery, it is a super-mobile original! Circuit board design science, high-quality devices, connection is very simple, diy digital products supply a good helper! Introduced： 1. Ultra-small size: PCB: 30mm * 18mm * 10mm 2. Back to the copper heat large, high-current work good heat dissipation, small interference 3. Need for input and output in all Sanyo POSCAP 470uF polymer capacitors, high frequency and high capacity TDK ceramic capacitors, the output ripple control in the low range. 4. Improved LED indication, more energy efficient, the battery voltage is lower than 2.7V, LED indicator light turns off. 5. The new version of the high-current step-up circuit using efficient booster circuit, with a good high-current MOS tube output current of 3A 6. Increase the voltage indicator 7. ripple less (50mV MAX) 8. higher efficiency (up to 92%) 9. band voltage indicator (input voltage is lower than 2.7V LED indicator off) Module parameters: Module Properties: non-isolated step-up module (BOOST) Input voltage: 3-5V (3V input voltage is less than the output current step to achieve rating) Output voltage: 5.0V (you can choose between 3-6V option if other voltages please inform the treasurer in advance, the default.The new version of the high-current step-up circuit using efficient booster circuit, with a good high-current MOS tube output current of 3A. Back to the copper heat large, high-current work good heat dissipation, small interference.
