DC to DC CC CV board is a 300KHz fixed frequency PWM step-down DC/DC module, capable of driving a 5A load with high efficiency, low ripple, and good load regulation. XL4015 E1 power converter is a high-power, high-efficiency, 5A output module with low ripple and a power indicator. Input range: DC 8V to 36V, output range: DC 1.25V to 32V. Features include over temperature protection, short circuit protection, and current limit protection; the module remains undamaged even during output short circuits. This DC-DC converter is suitable for testing multiple system operating voltage ranges, maintaining stable output voltage, and limiting output current across various input voltages. Ideal for general voltage conversion, battery charging, powering raw LEDs, automotive electronics, battery conversions, controllers, and electronic projects. Non-isolated constant current and constant voltage module with non-synchronous rectification. Input voltage: 836V (recommended not to exceed 36V) Output voltage: 1.2532V continuously adjustable Output current: 05A adjustable, recommended for use within 4.5A Working temperature: -40C to +85C Working frequency: 300KHz Output power: maximum 75W Conversion efficiency: up to 95% (efficiency varies based on input/output voltage, current, and voltage difference) Output ripple: max 50mV (20M bandwidth) Load regulation: 0.5% Voltage regulation: 2.5% Short circuit protection: Yes Over temperature protection: Yes (automatically disables output when overheated) Input reverse connection protection: None (external diode recommended if needed) Wiring: Terminal block or soldering; IN is input, OUT is output Size: 5.1 x 2.6 x 1.5 cm Material: ABS Color: As shown Package Contents: 10 x Down Charging Board Note: Only the items listed are included.
