EML3173 Datasheet - Elite Semiconductor

EML3173 Synchronous Step-Down DC-DC Converter

EML3173 is a high efficiency, DC-DC synchronous buck converter witch provides 3.0A output loading after output voltage reach preset voltage. EML3173 uses different modulation algorithms for various loading conditions. Under heavy load, EML3173 regulates the output voltage using Pulse Width Modulatio.
