Brand: QSKJ

Model:  QS-0305-3W

Features:

• Module uses the Taiwan production boost chip, high efficiency (up to 92%), plus built-in over-current protection chip, can be more good to protect the module and use the device after the class.

• Module with undervoltage protection, undervoltage protection into state below 2.5V, can be more better protect the battery, to avoid excessive discharge.

• Module can modify the fixed resistor adjusts the output voltage can be adjusted up to 12V output, but to ensure that the output power of less than 5W.

• This module uses multilayer ceramic capacitors as main filter capacitor, the output ripple can be as low as 20mV (5V1A output case)!

• This module uses a standard USB interface, you can use all universal USB charging mobile phones, MP3, MP4 and other equipment, the perfect support for IPHONE and other mobile phone.

Applications:

• DIY a mobile power supply, then only need to enter a battery-powered, you can output 5V voltage for your phone, MP3, MP4, PSP charger, very simple and convenient.

• In order to power your electronic devices when your device needs 5V power supply, when, however, only the section you are now in the hands lithium battery-powered, with our step-up to this module can be directly 5V, solve your problems.

• When you do a project when the input battery-powered (1-5V) time, and your system board and requires a 5V regulated power supply, then you choose this module we will be your best choice, debugging can not work directly on the machine, easy to achieve efficient high-power boost.
