RT7249
3A, 18V Synchronous Step-Down Converter with
Adjustable Current Limited Power Switch
General Description
Features
The RT7249 is a high efficiency, monolithic synchronous
step-down DC/DC converter with a power switch. The Buck
converter can deliver up to 3A output current from 4.5V to
18V input supply. The RT7249's current-mode architecture
and external compensation allow the transient response
to be optimized over a wide input range and loads. Cycleby-cycle current limit provides protections against shorted
output and soft-start eliminates input current surge during
start-up. The RT7249 also provides under-voltage protection
and thermal shutdown. PWM frequency is adjustable by
the ROSC pin and Power Switch current limit can also be
adjusted by the RLIM pin. The low current (
