RT7231 Overview
The RT7231/32/33/34 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 4A 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...
