XL4016 buck module 8A
Share :
XL4016 is a high-power, high-efficiency step-down (Buck) regulator primarily used to convert a higher DC input voltage into a lower, stable DC output voltage at high currents.
Features & Functions
- Topology: Step-Down (Buck) Regulator.
- Protection: Built-in Over-Temperature Protection (OTP) and Output Short-Circuit Protection (SCP).
- Load Regulation: Excellent line and load regulation.
- Output Adjustment: Requires external resistor divider network (R1 and R2) for setting output voltage: $V_{OUT} = 1.25V \times (1 + \frac{R1}{R2})$.
- Package: TO220-5L.
- Control: Includes an EN (Enable) pin for controlling ON/OFF state (Active High).
- The maximum input voltage for the XL4016 DC-DC converter is 40 Volts (V)
Typical uses for the XL4016 include:
High-Current Power Supplies: Stepping down 12V or 24V automotive or battery sources to standard regulated voltages (e.g., 5V or 3.3V) for microcontrollers, FPGAs, or other digital systems.
LED Driver Circuits: Due to its high current capability and regulation, it's often used to power large, high-power LED arrays that require constant current (though specialized LED driver ICs might be preferred for precise current control).
Battery Charging: Used in circuits that require high-efficiency charging of large lithium-ion or lead-acid batteries, where the voltage needs to be precisely controlled.
DIY/Hobbyist Power Modules: Integrated into popular high-current adjustable power modules frequently used in electronic projects and lab bench power supplies.
