Description

Voltage and current correspondence: Starting voltage 0.8V, output current 7MA Input 1-1.5V, output 5V 40-100MA Input 1.5-2V, output 5V 100-150MA Input 2-3V, output 5V 150-380MA Input more than 3V, output 5V 380-480MA This is a voltage boost converter module. When using it, be sure to observe the following conditions: The input voltage cannot be greater than the nominal voltage, otherwise the module will burn out The input power must be greater than the output power, otherwise the output voltage will be less than the nominal voltage The output load cannot be greater than the nominal load, otherwise the output voltage will be less than the nominal voltage Note: The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability. Please purchase carefully! Manual measurement, with small error. Please check size in detail before purchase. Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness. We highly appreciate all customers opinions to improve the selling, also if anything you unsatisfied, please contact us for probable best solution. Package Includes: 5Pcs

    • Very useful!
Used these to run a 5v Atmel ATtiny85 and an 8x8 LED matrix display from a 1.5v D-Cell battery. Worked great.

    • Really Tiny 5V Boost Converter, Very Low Power Operation Possible
I bought these to use with 3.7-4.2 V lithium ion batteries for projects where I needed 5V to run older electronics, specifically liquid crystal displays (LCDs). They are really tiny and easy to add to even the smallest project box. They have a significant current capability, but all of my applications are in the battery-operated, micro power range. Without an illuminating LED, most LCDs are in the sub-milliamp range unless updated at high rates. This boost converter uses a small inductor to generate a voltage above the input voltage. By themselves, these controllers draw a minimum no-load current of a few milliamps. I added a 2.5 mH hand-wound toroid inductor to the input wire to augment the inductance on the board, along with a 100 uF capacitor on the output for noise filtering. This dropped the no-load operating current to a fraction of a milliamp. That allowed using the LCD with about a milliamp of added current draw to the battery. There are probably a lot of other applications for these that involve higher currents, but small size and the possibility of very low quiescent current was why I bought them. ... show more

    • Used these to power a 5v device with a 3.7v source
Didn't quite work, but that's because I had too much current draw. The modules output 5v as described, I was just pushing them too hard. I will be using them in other projects though.

    • Great little booster

    • Great boosters
All 5 boosters worked just fine. Tested them as a Joule Thief with a green LED and 5.1K series resistor (draws around 0.5mA at 5V) as a load. All boosters managed to turn the LED on with as little as 0.52V on the input. And the maximum draw on the input was about 7mA which happens when the input voltage is on the low end (0.52V). At higher input voltages the input current to the booster is lower. ... show more

    • Not Useful
I had the same experience as reviewer Douglas M. Keenan (5/28/21). Using a single 18650 as input, the output was 5.5V with a 500mv sawtooth at about 7 KHz. Maybe some units work properly and this is just very bad quality control? A nuisance to have to test them all yourself ... Update: Using U1V10F5 from Pololu instead. ... show more

    • Small enough to fit d-cell flashlights
I use these to boost the voltage on several d-cell flashlights when used with led bulbs. Tight fit but it can be done.
