Dice Adjustable Power Supply Board DC Converter Buck Step Down

Description

Input: dc 3 v to 35 v (input voltage must be higher than to the output voltage of 1.5 v above.Can't step up)
Output: 35 V to 1.5 V dc voltage adjustable, high efficiency maximum output current is 3 a.
Features: all use solid-state capacitors, 36 u upset circuit boards, high Q value high power output inductor with LED lights
Working long hours recommended within 2.5 A current use, more than 2 A need to add heat sink (more than 10 w output);Because it is step-down module, in order to guarantee the stability of the output, please keep the minimum 1.5 V differential pressure.
Connection mode
1. The welding, welding the input (output) port directly to the power cord;2. The welding pin, can lead the insert pin or inserted in the hole hole plate use;Or add pins after welding on the PCB directly.
Application example
1. Automotive regulated power supply, this module input can only need to be connected to the car power supply point a cigarette holder, can adjust potentiometer, 1.25 30 v output voltage can be arbitrary adjustment, for your mobile phone, MP3, MP4, PSP charging many equipment such as power supply, very easy and convenient.
2. To the electronic equipment power supply, when a device needs 3-35 v power supply and corresponding voltage power in his hand, with this module can be adjusted the voltage to the voltage required, solve the problems.
3. The system operating voltage test, when doing project can use this module debugging the various working voltage range, voltage test system is very easy and convenient.
