EML3191
5A, 36V, 1.5MHz Non-synchronous Step-Down Converter
General Description
The EML3191 is frequency adjustable, 5A,
current-mode step-down converter with an
integrated high-side switch. The EML3191 operates
with the wide input voltage from 4.5V to 36V and
provides an adjustable output voltage from 0.808V
to 30V. The EML3191 features a PWM mode
operation with up to 1.5MHz adjustable switching
frequency. The EML3191 also provides a highly
efficient solution with current mode control for fast
loop response and easy compensation. The
EML3191 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.
