DS6257A

® RT6257A/B 6A, 18V, 500kHz, ACOTTM Step-Down Converter General Description Features The RT6257A/B is a high-efficiency, monolithic  4.5V to 18V Input Voltage Range synchronous step-down DC-DC converter that can deliver  6A Output Current up to 6A output current from a 4.5V to 18V input supply.  Constant-On-Time Mode to Enables Fast Transient The RT6257A/B adopts ACOT architecture to allow the Response transient response to be improved and keep in constant  Low Output Ripple and Allows Ceramic Output frequency. Cycle-by-cycle current limit provides protection Capacitor against shorted outputs and soft-start eliminates input  500kHz Switching Frequency current surge during start-up. Fault conditions also include  High Efficient Internal Power MOSFET Switch output under voltage protection and thermal shutdown. Optimized for Lower Duty Cycle Applications  Integrated 30mΩ/20mΩ MOSFETs Ordering Information RT6257A/B  Adjustable Output Voltage fro...
