EML3172 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT 3A, Synchronous Step-Down DC-DC Converter General Description EML3172 is a high efficiency, DC-DC synchronous buck converter which provides 3A output loading after output voltage reach preset voltage. EML3172 uses different modulation algorithms for various loading conditions. Under heavy load, EML3172 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 Save 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, EML3172...
