The power supply provides +\/- 5.50 V DC symmetrical outputs with load current 500mA from 5V DC input. The project is built using SN6505A IC from Texas instruments. The SN6505A is a low-noise, low-EMI push-pull transformer driver, specifically designed for small form factor, isolated power supplies. It drives low profile, center-tapped transformers 5 V DC power supply. Ultra-low noise and EMI are achieved by slew rate control of the output switch voltage and through Spread Spectrum Clocking (SSC). The SN6505 consists of an oscillator followed by a gate drive circuit that provides the complementary output signals to drive ground referenced N-channel power switches. The device includes two 1-A Power-MOSFET switches to ensure start-up under heavy loads. The internal protection features include a 1.7A current limiting, under-voltage lockout, thermal shutdown, and break-before-make circuitry. SN6505 includes a soft-start feature that prevents high inrush current during power up with large load capacitors.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInput Supply 5V DC\u003c\/li\u003e\n\u003cli\u003eOutput +\/- 5.50 V DC symmetrical outputs\u003c\/li\u003e\n\u003cli\u003eOutput Current 500mA Approx.\u003c\/li\u003e\n\u003cli\u003eUltra-Low EMI\u003c\/li\u003e\n\u003cli\u003eSpread Spectrum Clocking\u003c\/li\u003e\n\u003cli\u003ePrecision Internal Oscillator Options: 160 kHz (SN6505A)\u003c\/li\u003e\n\u003cli\u003eSlew-Rate Control\u003c\/li\u003e\n\u003cli\u003e7 A Current-Limit\u003c\/li\u003e\n\u003cli\u003eLow Shutdown Current: \u0026lt;1 μA\u003c\/li\u003e\n\u003cli\u003eThermal Shutdown\u003c\/li\u003e\n\u003cli\u003eWide Temperature Range: –55°C to 125°C\u003c\/li\u003e\n\u003cli\u003eSoft Start to reduce In-rush current\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":46962231869612,"sku":"G131","price":28.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/G131B.jpg?v=1787122593","url":"https:\/\/dotfry.com\/products\/isolated-power-supply-for-rs485-rs422-rs232-spi-i2c-and-power-lan","provider":"dotfry","version":"1.0","type":"link"}
