Dear, welcome to the Bigs, you will have a pleasant shopping experience here~ Any questions about the product can be consulted at any time, answer the questions online 24 hours a day. Descriptions: 1. LM2596 chip module uses high-quality , high efficiency (up to 92% ) , heat a small , can easily bring up 3A ( short ) over current, long working hours is recommended for use in less than 2.5A current , while adding fins (10W output above ) . 2. This module uses hine placement, reflow soldering, and each module before shipment after two hours of aging test, to ensure high reliability. 3. Input voltage range: DC 3.2V-40V (input voltage output voltage must be higher than 1.5V or more. Could not boost) 4. Output voltage range: 1.25V-35V DC voltage is continuously adjustable, high efficiency (up to 92%) the maximum output current of 3A. Specifications: Module property Non-isolation step-down (BU) Rectification mode Non-synchronous rectification. Input voltage 3.2V-40V Output voltage 1.25V-35V Input current 3A(maximum) Switching frequency 65KHz The output ripple 30mV(max.) Conversion efficiency 92%( highest) Load regulation ±0.5% Voltage regulation ±2.5% Work temperature -40℃ -- +85℃ Size 42*20*14(L*W*H)(mm) Note: 1. Long working hours is recommended for use in less than 2.5A current, while adding a heat sink (10W output above); due bu module, in order to ensure stable output, keep a minimum 1.5V differential. 2. This module is adjustable bu module; the module can be adjusted above sinking blue adjustable resistor to change the output voltage. Input and output pressure is 2V; the minimum can be output 1.25V voltage. 3. Modules indicated above IN-( negative input ), IN + ( positive input ), OUT-( negative output ), OUT + ( positive output ) be sure to pi the correct , otherwise it may cause damage to the module . 4. This module has no output short circuit protection, output short circuit if prolonged, may result in damage to the module.
