RT6254B - Step-Down Converter

Download the RT6254B datasheet PDF. This datasheet also covers the RT6254A variant, as both devices belong to the same step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The RT6254A/B is a high-performance, synchronous stepdown DC-DC converter that can deliver up to 4A output current from a 4.5V to 18V input supply.

The device integrates low RDS(ON) power MOSFETs, accurate 0.6V reference and an integrated diode of bootstrap circuit to offer a very compact solution.

Key Features

  • are also integrated in the device including the cycle-by-cycle current limit control, UVP, input UVLO and OTP. The RT6254A/B is available in the TSOT-23-6 (FC) and TSOT-23-8 (FC) package. Features.
  • 4.5V to 18V Input Voltage Range.
  • 4A Output Current.
  • Constant-on-Time Mode to Enables Fast Transient Response.
  • Low Output Ripple and Allows Ceramic Output Capacitor.
  • 500kHz Switching Frequency.
  • High Efficient Internal Power MOSFET Switch Optimized for Lower Duty Cycle App.

Reference Sample & Design Buy ® RT6254A/B 4A, 18V, 500kHz, ACOT® Step-Down Converter General Description The RT6254A/B is a high-performance, synchronous stepdown DC-DC converter that can deliver up to 4A output current from a 4.5V to 18V input supply. The device integrates low RDS(ON) power MOSFETs, accurate 0.6V reference and an integrated diode of bootstrap circuit to offer a very compact solution. The RT6254A/B adopts Advanced Constant On-Time (ACOT®) control architecture that provides ultrafast transient response and further reduces the externalcomponent count. In steady states, the ACOT® operates in nearly constant switching frequency over line, load and output voltage ranges and makes the EMI filter design easier.
