ETA2858 42V standoff, 5A Step-Down DCDC Synchronous Converter DESCRIPTION The ETA2858 is a high power, 42V standoff, 4.5-36V wide input range step-down DCDC converter. It integrates a low RDSON high side FET and a synchronous low side driver. With an external synchronous low side MOSFET, it strategically manages heat dissipation and is capable delivering more than 25W of power at the output, i.e. 5A current at 5V out. ETA2858 also includes CC/CV output regulation, output cord compensation, external programmable switching frequency for EMI optimization, making it a perfect solution for Car Charger application. ETA2858 is housed in a compact DFN3x3-12 package. FEATURES  42V standoff  4.
