EML3350-1.5A,60V,1.5MHz Non-synchronous Step-Down Converter DataSheet

General Description
    The EML3350 is a frequency adjustable, 1.5A,
current-mode step-down converter with an
integrated high-side switch. The EML3350 operates
with the wide input voltage from 4.5V to 60V and
provides an adjustable output voltage from 0.8V to
48V. The EML3350 features a PWM mode operation
with up to 1.5MHz adjustable switching frequency.
The EML3350 also provides a highly efficient solution
with current mode control for fast loop response and
easy compensation. The EML3350 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 EML3350 is available in E-SOP-8L with thermally
enhanced package.
