ESMT EML3171 2.0A, Synchronous Step-Down DC-DC Converter General Description EML3171 is a high efficiency, DC-DC synchronous buck converter which provides 2.0A output loading after output voltage reach preset voltage. EML3171 uses different modulation algorithms for various loading conditions. Under heavy load, EML3171 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 approaches the output voltage, EML3171 enters low dropout voltage operation under 100% duty cycle. The internal generated 0.
