General Description
The EML3350 is a frequency adjustable, 1.5A,current-mode step-down converter with anintegrated high-side switch. The EML3350 operateswith the wide input voltage from 4.5V to 60V andprovides an adjustable output voltage from 0.8V to48V. The EML3350 features a PWM mode operationwith up to 1.5MHz adjustable switching frequency.The EML3350 also provides a highly efficient solutionwith current mode control for fast loop response andeasy compensation. The EML3350 automaticallyenters PSM mode at light load. Cycle-by-cycle current limiting and thermalshutdown are provided for fault conditionprotections. An internal 2ms soft-start design reducesinput start-up current and prevents the outputvoltage and inductor current from overshootingduring power-up. The EML3350 is available in E-SOP-8L with thermallyenhanced package.
