LM2596S DC-DC Step-down Power Supply Module 3A Adjustable XL6009 Step-down Module Voltage Stabilizer DIP SMD

LM2596S DC-DC step-down power supply module BUCK 3A adjustable step-down module voltage stabilizer DIP/SMD

Features:

★ The module uses high-quality LM2596 chip, high efficiency (maximum 92%), low heat generation, and can easily bring current above 3A (short time). It is recommended to use current within 2.5A for long-term work, and add a heat sink at the same time (Output above 10W).

★ This module uses machine placement and reflow soldering. At the same time, each module undergoes a two-hour aging test before shipment to ensure high reliability.

★ This module has accumulated more than 15,000 pieces since it went on sale, and it still maintains a 100% favorable rate. It has been tested and received rave reviews. It is indeed the best choice for you to buy.

Input 3.2V-40V output 1.25V-35V

Input voltage range:

DC 3.2V-40V (The input voltage must be 1.5V higher than the output voltage. It cannot be boosted)

Output voltage range:

DC 1.25V-35V voltage is continuously adjustable, high efficiency (maximum 92%), maximum output current is 3A.

Precautions:

It is recommended to use the current within 2.5A for long-term work, and add a heat sink (output above 10W); as it is a step-down module, in order to ensure stable output, please maintain a minimum voltage difference of 1.5V.

★ This module is an adjustable step-down module, and the output voltage can be changed by adjusting the blue adjustable resistor on the module. The input and output voltage difference is 2V, and the minimum voltage can be 1.25V.

★ The IN- (input negative), IN+ (input positive), OUT- (output negative), and OUT+ (output positive) marked on the module must be connected correctly, otherwise the module may be damaged.

★ This module does not have output short-circuit protection. If the output is short-circuited for a long time, the module may be damaged.

Voltage regulation:

Connect the power supply (4-35V), adjust the blue potentiometer knob (usually turn clockwise to boost, counterclockwise to buck) and use a multimeter to monitor the output voltage until it reaches the required voltage.

Wiring:

1. Soldering, directly solder the power cord to the input (output) port

2. Welding pins can be used by inserting pins through lead wires or inserting into holes on the board; or directly soldering the PCB after adding pins.

Application examples:

1. Vehicle-mounted stabilized power supply, you only need to connect the input terminal of this module to the car cigarette lighter to supply power, you can adjust the potentiometer, and the output voltage can be adjusted at 1.25-30V, charging your mobile phone, MP3, MP4, PSP, etc. Many devices are supplied with power, which is very simple and convenient.

2. Supply power to electronic equipment. When the equipment needs 3-30V power supply and the corresponding voltage power supply in the hand, this module can be used to conveniently adjust the voltage to the required voltage to solve the problem.

3. System working voltage test. This module can be used to debug the working voltage range of various voltage test systems when doing projects, which is very easy and convenient.
