RT8253A 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 compensation 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 power...
