ESMT EML3173 3.0A, Synchronous Step-Down DC-DC Converter General Description 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 Modulation (PWM). The PWM mode provides low output voltage ripple and fixed frequency noise. While in light load, it enters Power Skip Modulation (PSM) automatically to ensure a highly efficient operation at light load condition. Under very heavy load condition, or when the input voltage Features „ „ „ „ „ „ „ „ Wide Operating Voltage Ranges : 2.6V to 5.5V 3.
