LM2596 Mini 360 Aircraft Power Supply Step-down Module Pinout Explanation
The LM2596 Mini 360 Aircraft Power Supply Step-down Module is a compact DC-DC converter module designed to step down higher voltage inputs to a stable lower voltage output. This module features a high-performance LM2596 regulator IC, which provides high efficiency and reliability. Here's a detailed explanation of each pin:
Pinout Structure:
The module has a total of 5 pins, arranged in a single row. The pins are labeled as follows:
1. VIN (Input Voltage)
2. GND (Ground)
3. VOUT (Output Voltage)
4. EN (Enable)
5. ADJ (Adjust)
Pin-by-Pin Explanation:
1. VIN (Input Voltage)
Function: Input voltage pin, where the unregulated DC power source is connected.
Recommended Input Voltage Range: 7V to 40V DC
Note: Ensure the input voltage is within the recommended range to maintain the module's efficiency and prevent damage.
2. GND (Ground)
Function: Ground pin, which provides a common reference point for the module's circuitry.
Connection: Connect to the negative terminal of the input power source or a common ground point in your system.
3. VOUT (Output Voltage)
Function: Output voltage pin, which provides the regulated DC output voltage.
Default Output Voltage: 5V (adjustable via the ADJ pin)
Note: The output voltage can be adjusted using the ADJ pin, but ensure the output voltage is within the recommended range for your application.
4. EN (Enable)
Function: Enable pin, which allows the module to be turned on or off.
Logic Level: Active High (connect to VIN or a logic high signal to enable the module)
Note: Leaving the EN pin unconnected or tied to GND will disable the module.
5. ADJ (Adjust)
Function: Adjust pin, which allows the output voltage to be adjusted.
Connection: Connect a resistor divider network between VIN and GND, with the center tap connected to the ADJ pin. This allows the output voltage to be adjusted within a certain range.
Recommended Connection Structure:
VIN: Connect to a suitable unregulated DC power source (e.g., a battery or wall adapter).
GND: Connect to the negative terminal of the input power source or a common ground point in your system.
VOUT: Connect to the load that requires the regulated output voltage (e.g., a microcontroller or sensor).
EN: Connect to VIN or a logic high signal to enable the module, or leave unconnected or tied to GND to disable it.
ADJ: Connect a suitable resistor divider network to adjust the output voltage (optional).
When connecting the pins, ensure that the module is properly secured to a heat sink or a metal surface to prevent overheating. Additionally, follow proper safety precautions when working with electrical circuits to avoid electrical shock or injury.
