SEMIPICK - EML3420 Datasheet / The EML3420 is a frequency adjustable, 6A, current-mode step-down converter with an integrated high-side switch. The EML3420 operates with the wide input voltage from 4.5V to 40V and provides an adjustable output voltage from 0.8V to 30V. The EML3420 features a PWM mode operation with up to 2.1MHz adjustable switching frequency. The EML3420 also provides a highly efficient solution with current mode control for fast loop response and easy compensation. The EML3420 automatically enters PSM mode at light load. Cycle-by-cycle current limiting and thermal shutdown are provided for fault condition protections. An internal 2ms soft-start design reduces input start-up current and prevents the output voltage and inductor current from overshooting during power-up. The EML3420 is available in E-SOP-8L with thermally enhanced package.
