RT6206B Datasheet | Richtek

® 5.5A, 18V, 650kHz, ACOTTM Synchronous Step-Down Converter General Description The RT6206B is a synchronous step-down DC/DC converter with Advanced Constant On-Time (ACOTTM) mode control. It achieves high power density to deliver up to 5.5A output current from a 4.5V to 18V input supply. The proprietary ACOTTM 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, RT6206B keeps an excellent constant switching frequency under line and load variation and the integrated synchronous power switches with the ACOTTM mode...
