EML3421 - 2.1MHz Non-synchronous Step-Down Converter

Description

The EML3421 is a frequency adjustable, 6A, current-mode step-down converter with an integrated high-side switch.

The EML3421 operates with the wide input voltage from 4.5V to 40V and provides an adjustable output voltage from 0.8V to 30V.

Features

  • a PWM mode operation with up to 2.1MHz adjustable switching frequency. The EML3421 also provides a highly efficient solution with current mode control for fast loop response and easy compensation. The EML3421 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 powe.
