EML3193B-3A,36V,2MHz Non-synchronous Step-Down Converter DataSheet

General Description
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.
