ETA2858
ETA2858 is 5A Step-Down DCDC Synchronous Converter manufactured by ETA.
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 pensation, external programmable switching frequency for EMI optimization, making it a perfect solution for Car Charger application.
ETA2858 is housed in a pact DFN3x3-12 package.
