This board accepts a wide input voltage range of \u003c\/span\u003e\u003cstrong\u003e12V to 76V DC\u003c\/strong\u003e\u003cspan\u003e and generates a regulated \u003c\/span\u003e\u003cstrong\u003e5V DC\u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003eoutput. The BD9G341AEFJ features an integrated \u003c\/span\u003e\u003cstrong\u003e150mΩ N-channel MOSFET\u003c\/strong\u003e\u003cspan\u003e and a programmable switching frequency, adjustable from \u003c\/span\u003e\u003cstrong\u003e50kHz to 750kH\u003c\/strong\u003e\u003cspan\u003ez. On this board, the switching frequency is fixed at \u003c\/span\u003e\u003cstrong\u003e200kHz\u003c\/strong\u003e\u003cspan\u003e using resistor \u003c\/span\u003e\u003cstrong\u003eR5.\u003c\/strong\u003e\u003cspan\u003e To ensure reliable operation, the board incorporates several protection features. A fixed soft-start circuit minimizes inrush current during startup. Additionally, the board includes Under-Voltage Lockout (UVLO), Thermal Shutdown Detection (TSD), Over-Current Protection (OCP), and Over-Voltage Protection (OVP) circuits. The UVLO threshold and hysteresis are configured externally using resistors R1 and R4 connected to the EN (Enable) pin.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInput 12V to 76V DC\u003c\/li\u003e\n\u003cli\u003eOutput 5V DC\u003c\/li\u003e\n\u003cli\u003eOutput Current 2A, up to 3A (Read Note)\u003c\/li\u003e\n\u003cli\u003eOperating Frequency 200Khz\u003c\/li\u003e\n\u003cli\u003eOn Board Power LED\u003c\/li\u003e\n\u003cli\u003ePrecision EN\/UVLO Threshold +\/-3%\u003c\/li\u003e\n\u003cli\u003eUnder Voltage Lockout (UVLO), Threshold 11V\u003c\/li\u003e\n\u003cli\u003eSoft Start Function (20mS)\u003c\/li\u003e\n\u003cli\u003eOver Current Protection (OCP)\u003c\/li\u003e\n\u003cli\u003eThermal Shutdown (TSD)\u003c\/li\u003e\n\u003cli\u003eOver Voltage Protection (OVP)\u003c\/li\u003e\n\u003cli\u003eScrew Terminals for Power Input and Output\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions 45.09 x 19.84 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":46900437581996,"sku":"G114","price":23.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/G114A.jpg?v=1786192034","url":"https:\/\/dotfry.com\/products\/buck-converter-12v-76v-input-5v-dc-output","provider":"dotfry","version":"1.0","type":"link"}
