The module incorporates several protection features, making it ideal for various applications requiring efficient and adjustable DC power.

Key Features

- Wide Input Voltage Range: Accepts DC voltages from 5V to 36V.

- Adjustable Output Voltage: Output voltage can be adjusted from 1.25V to 32V.

- High Efficiency: Achieves efficiency up to 96%, minimizing energy loss.

- Overcurrent Protection: Includes overcurrent protection to prevent damage from excessive current draw.

- Short Circuit Protection: Built-in protection against output shorts.

- Thermal Shutdown: Automatically shuts down in case of overheating.

- LED Display: Includes an LED display for monitoring voltage/current/power.

- Constant Current and Constant Voltage Modes: Supports both constant current (CC) and constant voltage (CV) modes, indicated by an LED.

- USB Port: Includes a USB port for charging digital devices (output voltage is the same as the module's output voltage).

Versatile Applications and Benefits

- General DC Power Conversion: Can be used as a general-purpose step-down power supply.

- LED Driver: Suitable as a constant current LED driver module.

- Battery Charging: Can be used as a battery charger for various battery types (solar panels, wind-driven generators).

- Adjustable Power Supply: Ideal for creating adjustable power supplies for electronics projects.

- Mobile Power: Can be used in DIY mobile power bank projects.
