3Pcs 3V To 5V 1A USB Charger DC-DC Converter Step Up Boost Module 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 TDK 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. Specification: Module properties: Non-isolated step-up module (BOOST) Input voltage: 2.5-6V Output voltage: 4-12 V(Adjustable, the default 5 v) Output current: 1000mA (Max) Efficiency: 92%(Max) (the higher the input voltage, the higher the efficiency) Switching frequency: 1MHz Output ripple: 20mV (MAX) Operating temperature: Industrial (-40°c to +85°c) Voltage regulation: ±2.5% Short circuit protection: None (please use the lithium battery with protection) Input: IN + postive, IN - negative Output: USB output Size: 3 x 1.3 x 0.8 cm Application: This module can be used for DIY mobile power output, enabling single or two ordinary lithium battery to 5V boost to the mobile phone or PSP device charging. DIY a mobile power supply, only need one battery, you can output 5V voltage for your phone, MP3, MP4, PSP charger, very easy. In order to power your electronic devices when your device needs 5V power supply, when you only have lithium battery, this module can be directly step-up to 5V, solve your problems. Note: This module is a fixed 5V output module Modules indicated above IN - (negative input), IN + (positive input), OUT-(negative output), OUT + (positive output) must be connected correctly, otherwise it may cause damage to the module This module has an LED light, when the charge when the LED lights can be used as indicator Package included: 3 x USB boost module
