It is LM2596 HV DC-DC Buck Converter with voltage rating 4.5-40V to 3-35V. This step down power module is adjustable with a potentiometer.

Features:

1. Adjustment method: first correct input power (between 4.5-50V) then multimeter to monitor the output voltage and adjust potentiometer (usually clockwise turn boost, buck turn counterclockwise),
2. Input: IN+ input positive IN- input negative
3. Output: OUT+ output positive OUT- output negative
4. Static power consumption is only about 6mA.
5. Connection: Welding, plus pin can be directly soldered after the PCB.
6. Short circuit protection: current limiting, thermal protection, self-recovery.
7. Non-isolated step-down (BUCK) switching regulator.
8. Short circuit protection: Current limiting, self-recovery
9. Potentiometer adjustment direction is as Clockwise (increase) and Anti-clockwise (decrease)
10. Non-synchronous rectification

Product Specification Product DescriptionDescriptions:

The CP2102 is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS-232designs to USB using a minimum of components and PCB space. The CP2102 includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, EEPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5 x 5 mm MLP-28 package.The CP2102 UART interface implements all RS-232 signals, including control and handshaking signals, so existing system firmware does not need to be modified. In many existing RS-232 designs, all that is required to update the design from RS-232 to USB is to replace the RS-232 level-translator with the CP2102.

Features of CP2102

• Included USB transceiver, without external circuit device
• Includes a clock circuit, no external circuitry
• Includes power-on reset circuit

Product Specification Product DescriptionQUICK OVERVIEW

1. Input Voltage(VDC): 4 ~ 40.
2. Output Voltage(VDC): 1.3 ~ 37.
3. Output Current: 2A Rated, ( 3A maximum with heat sink).
4. Switching Frequency: 150 kHz.
5. Input reverse polarity protection.
6. Built-in output short protection function.

This is LM2596 2A Buck Step-down Power Converter Module DC 4 ~ 40 to 1.3 ~ 37V, it comes with a built-in voltmeter display and uses an advanced microcontroller.

Together with its high precision multi-turn potentiometer, this means any desired output voltage within its supply range can be set without the need for an external voltage meter. The module also boasts a very high operating range with a DC input supply range of 4 ~ 40V and an adjustable output range of 1.3 ~ 37V.

Output voltage calibration steps:

Step 1: Adjust the right button so that “OUT” LED lighted, the voltmeter shows the value of output voltage; Press the right button for more than 2 seconds, release, voltmeter and “OUT” LED flashes in synchronization so that you enter the output voltage calibration mode.

Step 2: Press the right button (normal speed), the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press.

Step 3: Press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters set to automatically power down to save.

Input voltage calibration steps:

Step 1: Adjust the right button so that “IN” LED lighted, the voltmeter shows the value of input voltage; press the right button for more than 2 seconds, release, voltmeter and “IN” LED flashes in synchronization so that you enter the input voltage calibration mode.

Steps 2 and 3, consistent with the output voltage calibration method.

Notes: Maximum current is dependent on input and output voltages, ambient temperature and cooling. To achieve maximum ratings an external heatsink may be required. Maximum LM2596 operating temperature must not exceed 125°C otherwise permanent thermal damage can occur.Features :

1. Input reverse polarity protection
2. Built-in output short protection function
3. The built-in thermal shutdown function
4. Press the right key to let the display show the input or output voltage. when the right “OUT” led light, it shows output, the left “IN” led show input.
5. Power-off memory function, show that road after power voltage values measured for the last time
6. Press the touch button for 3 seconds to turn off the LED display, touch the button again to turn on the LED display
7. The band terminals, no iron can also be easy to use, and retention wire connection point

Package Includes :
