The EML3193B is a frequency adjustable, 3 A, current-mode step-down converter with an integrated high-side switch. Made by Elite Semiconductor Memory Technology (ESMT), the device operates across a wide input voltage from 4,5 V to 36 V and provides an adjustable output voltage from 0,808 V to 30 V.
The converter features PWM mode operation with up to 2 MHz adjustable switching frequency, and 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 protection. An internal 2 ms 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 and TDFN-10L thermally enhanced packages.
