The project is built using a \u003cstrong\u003eTLD1211\u003c\/strong\u003e chip from \u003cstrong\u003eInfineon. \u003c\/strong\u003eThe board provides supply to LEDs under the severe condition of automotive applications resulting in constant brightness and extended LED lifetime. The project is capable to drive high current, high brightness LEDs. The circuit features overload, short circuit, over-voltage, and over-temperature protections. It also has the option to control the LED brightness control by an external PWM signal.\u003c\/p\u003e\n\u003cp\u003eThe project can provide an output current of up to \u003cstrong\u003e2.5A\u003c\/strong\u003e. You will need to choose the appropriate booster transistor Q1 and sunt resistor R5 to achieve this output. Please refer to the datasheet of the chip for more info.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOperating Voltage 8 to 24V (Maximum 28V)\u003c\/li\u003e\n\u003cli\u003eLoad Current 300mA\u003c\/li\u003e\n\u003cli\u003eConstant Current Output\u003c\/li\u003e\n\u003cli\u003eEnable Input for PWM Brightness or ON\/OFF\u003c\/li\u003e\n\u003cli\u003eOver Voltage Protection\u003c\/li\u003e\n\u003cli\u003eVery low Standby Current\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions 36.04 x 22.54mm\u003c\/li\u003e\n\u003cli\u003e2 x 2.5mm Mounting Holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConnections and Other Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCN1: Pin 1,2 = VCC, Pin 3, 4 = GND\u003c\/li\u003e\n\u003cli\u003eCN2: Pin 1 = Enable or PWM Enput, Pin 2 = GND\u003c\/li\u003e\n\u003cli\u003eCN3: Pin 1, 2 = +LED , Pin 3,4 = -LED\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47249164173484,"sku":"B151","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/B151.jpg?v=1789889622","url":"https:\/\/dotfry.com\/products\/linear-current-source-led-driver-with-dimmer-input","provider":"dotfry","version":"1.0","type":"link"}
