RT7238C - 500kHz Synchronous Step-Down Converter

Download the RT7238C datasheet PDF. This datasheet also covers the RT7238B variant, as both devices belong to the same 500khz synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

Description

The RT7238B/C/D/E is an advanced constant on-time (ACOTTM) mode synchronous step-down converter.

The main control loop of RT7238B/C/D/E using an advanced constant on-time (ACOTTM) mode control which provides a very fast transient response.

The RT7238B/C/D/E operates from 8V to 23V input voltage.

Features

  • Advanced Constant On-Time (ACOT) Control.
  • 8V to 23V (RT7238B/C/D/E) Input Voltage Range @ 8A Output Current.
  • ACOTTM Mode Performs Fast Transient Response.
  • ACOTTM Architecture to Enable all MLCC Output Capacitor Usage.
  • Fixed 500kHz Switching Frequency.
  • High Efficient Internal Power MOSFET Switch  27mΩ (High-Side) and 10mΩ (Low-Side).
  • Adjustable Output Voltage from 0.6V to 5V (RT7238D).
  • Fixed 3.3V (RT7238B/D) or 5V (RT7238C/E) LDO Output Supplies 70mA.
