DC-DC Booster Step Up Converter 3.7V-4.2V to 5V 8V 9V 12V Output mini power supply


This DC-DC boost power supply module steps up any input voltage from 2.5V~VOUT to the output voltage of 5V/8V/9V/12V(default to 12V) at a conversion efficiency over 80%.


With a compact size, it can be well integrated into devices. There are two pads with the letters A & B on the front side of the module, and users can use a soldering iron to change the pads connection to set voltage output. Besides, it has an on-board power indicator that visually shows the working status. This module can be widely used in battery boost, power supply modification, car driving, LED lighting, etc.


Voltage Output Selection
There are two pads with the letters A & B on the front side of the module, and users can use a soldering iron to connect/disconnect them to set voltage output. For the specific mode, please refer to the information on the back.


Description:
1. The output voltage can be set to 5V/8V/9V/12V, the default is 12V
2. Input voltage range: 2.5V~VOUT. The input voltage must be lower than the set output voltage
3. Output capacity: when input with 3.7V lithium battery, it can output 5V1A, 8V0.5A, 9V0.45A, 12V0.3A
4. When using 5V input, it can output 8V0.7A, 9V0.7A, 12V0.5A
5. When the default output is 12V, the LED indicator consumes about 1mA.
6. If the indicator light is turned off, the input current is 1mA when no load.
7. Dimensions: 22 mm x 11 mm.
