EML3193B-00FH10NRR
The EML3193B is frequency adjustable, 3A, current-mode step-down converter with an integrated high-side switch. The EML3193B operates with the wide input voltage from 4.5V to 36V and provides an adjustable output voltage from 0.808V to 30V. The EML3193B features a PWM mode operation with up to 2MHz adjustable switching frequency. The EML3193B also provides a highly efficient solution with current mode control for fast loop response and easy compensation. The EML3193B 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 EML3193B is available in E-SOP-8L with thermally enhanced package.
