® RT7266 3A, 18V, 700kHz ACOTTM Synchronous Step-Down Converter General Description The RT7266 is an adaptive on-time ACOT TM mode synchronous buck converter. The adaptive on-time ACOTTM mode control provides a very fast transient response with few external components. The low impedance internal MOSFET can support high efficiency operation with wide input voltage range from 4.5V to 18V . The proprietary circuit of the RT7266 enables to support all ceramic capacitors. The output voltage can be adjustable between 0.8V and 8V. The soft-start is adjustable by an external capacitor.
