General Description

The RT7240A is a synchronous step-down DC/DC converter with Advanced Constant On-Time (ACOT®) mode control.

It achieves high power density to deliver up to 5A output current from a 4.5V to 18V input supply.

The proprietary ACOT®mode offers an optimal transient response over a wide range of loads and all kinds of ceramic capacitors, which allows the device to adopt very low ESR output capacitor for ensuring performance stabilization.

Key Features

  • ACOT®Mode Enables Fast Transient Response.
  • 4.5V to 18V Input Voltage Range.
  • 5A Output Current.
  • 35mW Internal Low Site N-MOSFET.
  • Advanced Constant On-Time Control.
  • Support All Ceramic Capacitors.
  • Up to 95% Efficiency.
  • Discontinuous Operating Mode at Light Load.
  • Adjustable Output Voltage from 0.765V to 8V.
  • Adjustable Soft-Start.
  • Cycle-by-Cycle Current Limit.
  • Input Under Voltage Lockout.
  • Thermal Shutdown.
