Introduction

The RT7238B/C/D is an advanced constant on-time (ACOT) mode synchronous step-down converter. The main control loop of RT7238B/C/D using an advanced constant on-time (ACOT) mode control which provides a very fast transient response. The RT7238B/C/D operates from 8V to 23V input voltage. For the RT7238D, the output voltage can be adjusted between 0.6V to 5V. The RT7238B/C/D is available in the UQFN-10L 3x3 (FC) package.
