DS6257B - Step-Down Converter

Download the DS6257B datasheet PDF. This datasheet also covers the DS6257A variant, as both devices belong to the same step-down converter family and are provided as variant models within a single manufacturer datasheet.

Key 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 pro.
