DC-DC Boost Power Supply Module Converter Booster Step Up Circuit Board Module DC 3V To DC 5V Highest Efficiency 92%

DC-DC Boost Power Supply Module Converter Booster Step Up Circuit Board Module DC 3V to DC 5V Highest Efficiency 92% Feature: Module Properties: Non-Isolated Boost Module (BOOST) Input voltage: 3-5V (the input voltage is le than 3V and the output current step can reach the rated value) Output voltage: 5.0V (choose between 3-6V, if other voltages, please notify the shopkeeper in advance, the default delivery is 5V) Output current: rated 3A (input voltage greater than 3V), short-term 5A (le than 10 seconds) Conversion Efficiency: Up to 92% (The higher the input voltage, the higher the efficiency) Please see the test chart below Switching frequency: 500KHz Output rple: Input 4.2V Output 5V 3A 40mV (MAX) Input 3.7V Output 5V 3A 50mV (MAX) 20M bandwidth Undervoltage indication: load LED is on (input voltage is lower than 2.7V LED is off) Operating temperature: Industrial (-40°C to +85°C) (output current within 1A when ambient temperature is 85°C) Full load temperature rise: 40℃ Quiescent current: 200uA Load Regulation: ±1% Voltage regulation: ±0.5% Dynamic response speed: 5% 200uS Short circuit protection: No need, if you want short circuit protection, you can enter the lithium battery protection board or use a protected lithium battery. Input re polarity protection: No, if you need re polarity protection, please use our re polarity protection board. Wiring method: , D-24 standard package, can be directly soldered on the (pins need to be installed, the shop owner makes the purchase) Input method: IN + input positive, IN- input negative Output: OUT+ output is positive, OUT- output is negative Introduction This power module is the core components that we have carefully designed and ed. Using ch technology, DC-DC 3V 5V boost circuit with USB output, wide working range, stable 5V/3A circuit froV-5V output, provides a good way to charge mobile phones, MP3, MP4, PSP, mobile devices! Use 2 AA/5 batteries, can charge mobile phone MP3, MP4. Coupled with a high-capacity lithium battery, it's a super mobile ! The circuit board design is scientific, the equment quality is high, and the connection is very simple. It is a good helper for DIY digital power supply! 1. Ultra-small size: circuit board: 30mm×18mm×10mm 2. Large copper heat diation on the back, high current work heat diation, little interference 3. The input and output all use the best Sanyo POSCAP 470uF polymer s and TDK high-capacity ceramic s, and the output rple is controlled within a very low range. 4. Improve the LED indicator, more energy-saving, the battery voltage is lower than 2.7V, the LED indicator is off. 5. The new version of the high-current booster circuit adopts a high-voltage booster circuit, which has a good output current of 3A for the high-current MOS tube. Application: 1). DIY is a mobile power supply, you only need to input battery power, you can output 5V voltage for your mobile phone, MP3, MP4, PSP charging, very simple and convenient. 2). Boost charger, you can use 2 AA batteries or Lithium batteries as a 5V device. 3). However, for your electronics, when your device needs 5V power, all you need now is a handheld Li-Ion battery. With our module, we can directly boost to 5V to soe your problem. 4) The pre-power supply of the system, when you are working on a project, enter the battery power supply (1-5V), and your system needs a 5V stable power supply, then your choice of our module will be your best choice, please Do not directly debug on the hine, and easily achieve high-efficiency and high-power improvement. Package List: 1 x DC-DC boost model
