Broadcasting launched a new core source oscillation frequency is 280K, ultra-high efficiency DC boost regulator circuit SC3682. The chip oscillation frequency is low in the circuit design can be easily done products CE FCC and other safety certification. Circuit structure can be easily automated Buck-Boost design, single input positive negative output circuit, low rise ultrahigh voltage 100V applications. Minimum input voltage range can be up to 2.7 volts to 30 volts, the output voltage and the internal MOS 3.3--40V adjustable output switch current up to 2A, ideal for battery-powered portable products to digital, 3G network products, digital cameras, LCD LCD backlight circuit, solar street lighting, network communications products such as voltage conversion. SC3682 standard of ESOP-8 lead-free package, the application circuit is very simple, very few external components.
