Description:
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 shipping is 5V)
Output Current: Rated 3A (input voltage greater than 3V), short 5A (less than 10 seconds)
Conversion efficiency: up to 92% (the higher the input voltage, the higher the efficiency) a detailed look at the following test pattern
Switching Frequency: 500KHz
Output ripple:
Input 4.2V Output 5V 3A 40mV (MAX)
Input 3.7V Output 5V 3A 50mV (MAX)
20M Bandwidth
Voltage indication: LED lights with a load (input voltage is lower than 2.7V LED indicator off)
Operating temperature: Industrial grade (-40 ℃ to + 85 ℃) (ambient temperature is 85 degrees or less output current 1A)
Full load temperature rise: 40 ℃
Quiescent Current: 200uA
Load regulation: ± 1%
Voltage regulation: ± 0.5%
Dynamic response speed: 5% 200uS
Short circuit protection:
None, if you have a short-circuit protection can enter installed lithium battery protection board, or use a lithium battery with protection.
Input Reverse Polarity Protection: None
Connection: Welding, DIP-24 standard package can be soldered directly to the PCB
Input: IN + input positive , IN- input negative
Output : OUT + output positive , OUT- output negative
Package Included:
1PC*DC-DC Boost Converter 3V 3.7V 4.2V to 5V 3A Power Supply Step Up Circuit Module
