XL4015 E1 power converter is a power, efficiency DCDC buck module with 5A output capability and a low ripple profile, complemented by a power indicator for quick status checks. Key benefits power and efficiency: supports demanding loads with stable, efficient operation, suitable for bench testing and development. Stable voltage across ranges: a versatile DCDC converter that can debug multiple operating voltage ranges, maintain a stable output voltage, and limit output current over a wide input voltage range. Efficient 300 kHz switching: the board uses a fixedfrequency PWM buck topology at 300 kHz, delivering efficiency, low ripple, and strong line and load regulation while driving up to 5A. Robust protection: input 8V to 36V, output adjustable from 1.25V to 32V, with overheating protection, short circuit protection, and current limit protection; even in a shortcircuit condition, the module will not be damaged. Specifications at a glance Input voltage: DC 8V 36V Output voltage: DC 1.25V 32V Output current: up to 5A Switching frequency: 300 kHz fixedfrequency PWM Protections: overheating, short circuit, current limit; shorted output will not damage the module Applications and use scenarios Multirail development and debugging: provide stable voltages for development boards and embedded systems requiring different voltage rails, while limiting current to protect sensitive components. Variableinput bench testing: accommodate systems whose supply varies from 8V to 36V, delivering a stable output voltage for reliable testing and validation. 5A load bench power: power motors, motor drivers, LED drivers, or other current loads in a lab or prototyping environment with builtin protection to prevent damage from faults.
