The built-in frequency dithering further reduces the EMI noise spectrum.  The RAA223012 also features input brownout protection that prevents input circuitry from the overcurrent at low input voltage, and hiccup protections for output fault conditions such as short-circuit, overload, and open feedback.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal Input 85V to 265V AC 50\/60Hz\u003c\/li\u003e\n\u003cli\u003eOutput 5V DC, 150mA\u003c\/li\u003e\n\u003cli\u003eOutput Short Circuit Protection\u003c\/li\u003e\n\u003cli\u003eOverload Protection (OLP)\u003c\/li\u003e\n\u003cli\u003eShort-Circuit Protection (SCP)\u003c\/li\u003e\n\u003cli\u003eOpen Feedback Protection\u003c\/li\u003e\n\u003cli\u003eOver-Temperature Protection (OTP)\u003c\/li\u003e\n\u003cli\u003e4 x 2.5mm Mounting Holes\u003c\/li\u003e\n\u003cli\u003ePCB dimensions 52.07 x 28.58 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":46962389385388,"sku":"G135","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/G135A.jpg?v=1787127708","url":"https:\/\/dotfry.com\/products\/universal-input-ac-dc-switching-buck-regulator-85v-265v-ac-input-5v-150ma-dc-output","provider":"dotfry","version":"1.0","type":"link"}
