XL4015 DC-DC Adjustable Step-down Module, which is a buck converter used to step down a higher input voltage to a lower, adjustable output voltage.
Features
- Function: It is a fixed-frequency PWM buck (step-down) DC/DC converter. It is capable of driving a 5A load with high efficiency and low ripple.
- Voltage Range: It has an input voltage range of 4V to 38V and an adjustable output voltage range of 1.25V to 36V.
- Protection: The module includes built-in overcurrent protection and thermal shutdown protection. When a short circuit occurs, the operating frequency is reduced from 180 KHz to 48 KHz.
- Efficiency: The module has a maximum efficiency of 96%.
- Control: The PWM control circuit can linearly adjust the duty ratio from 0% to 100%.
- Applications: It can be used for various applications where the input voltage is higher than the output voltage, such as in DIY adjustable power supplies, battery chargers, and high-power LED constant current drive modules.
