EML3190 - 420kHz Non-synchronous Step-Down Converter

Description

The EML3190 is a 5A, current-mode step-down converter with an integrated high-side switch.

The EML3190 operates with the wide input voltage from 4.5V to 36V and provides an adjustable output voltage from 0.808V to 30V.

Features

  • a PWM mode operation with internally fixed 420kHz switching frequency. The EML3190 provides a single highly efficient solution with current mode control for fast loop response and easy compensation. The EML3190 also 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 duri.
