RT7249 Datasheet | Richtek

® 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 pensation 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...
