RT7231/32/33/34
4A, 18V, 650kHz, ACOT® Synchronous Step-Down Converter
General Description
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 performance stabilization. In addition, RT7231/32/33/34 keeps an excellent constant switching frequency under line and load variation...
