EML3190
5A, 36V, 420kHz Non-synchronous Step-Down Converter
General 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. The EML3190 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
during power-up.
The EML3190 requires a minimum number of external
components and is available in E-SOP-8L with
thermally enhanced package.
