In constant-voltage mode, it supplies a regulated voltage that can be adjusted via a potentiometer or external signals; in constant-current mode, it limits the current flow to a fixed set value. With maximum output currents of up to 5 A, the module is suitable for more demanding applications than simple linear regulators.\u003c\/p\u003e \u003cp\u003eThe XL4005 switching regulator operates at a switching frequency of approximately 150 kHz and uses high-frequency pulse-width modulation for voltage regulation. This enables high efficiency and lower heat generation than linear circuits. Continuously adjusting the output voltage via a voltage-divider potentiometer provides complete control over the output level.\u003c\/p\u003e \u003cp\u003eThe module can be used for charging lithium-ion batteries in constant-current mode, for stabilized power supply to LED strips and light-emitting actuators, and for prototype power supplies for systems with variable or dynamic current requirements. The regulator can also be used as a laboratory-controlled current source for test measurements or as charging electronics in self-sufficient energy systems.\u003c\/p\u003e \u003cp\u003eOperation requires an input voltage source in the range of 5 to 32 V. The output current and output voltage are defined by external resistors or the potentiometer, respectively. The parameters to be set can be calculated from the XL4005 IC datasheet. Ensure correct polarity when assembling the circuit.\u003c\/p\u003e \u003ch3\u003eSafety information\u003c\/h3\u003e \u003cp\u003eThe input voltage must be between 5 and 32 V DC. Incorrect polarity will permanently damage the module. The device is intended exclusively for building prototypes and for testing and development purposes and is not suitable for installation in the household power circuit. Work on or near electrical installations must be carried out by qualified electricians; if in doubt, consult a qualified electrician before commissioning.\u003c\/p\u003e \u003ch4\u003ePackage contents\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x Constant-current \/ constant-voltage step-down XL4005 5A DC-DC adjustable\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65997825573213,"sku":"F23105924","price":4.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/konstantstrom-konstantspannung-stepdown-xl4005-5a-dc-dc-einstellbar-funduino-8034504.png?v=1791493614","url":"https:\/\/funduino.com\/en\/products\/constant-current-constant-voltage-step-down-xl4005-5a-dc-dc-adjustable","provider":"Funduino","version":"1.0","type":"link"}
