Product Description
Description:
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 machine 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.

Note:
1. Long working hours is recommended for use in less than 2.5A current, while adding a heat sink (10W output above); due buck module, in order to ensure stable output, keep a minimum 1.5V differential.
2. This module is adjustable buck 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 pick 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.
Included:
1 x Regulator Power Module
