RT8253A Datasheet | Richtek

3A, 23V, 340kHz Synchronous Step-Down Converter General Description The RT8253A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 23V input supply. The RT8253A's current mode architecture and external pensation allow the transient response to be optimized over a wide range of loads and output capacitors. Cycle by cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start up. Fault conditions also include output under voltage protection and thermal shutdown. The low current (<3 μ A) shutdown mode provides output disconnect, enabling easy...
