RT7249
3A, 18V Synchronous Step-Down Converter with Adjustable Current Limited Power Switch
General Description
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...
