1.5A, 18V, 500kHz ACOT™ Synchronous Step-Down Converter
The RT7285/A is a synchronous step-down converter with Advanced Constant ,On-Time (ACOTTM) mode control. The ACOTTM provides a very fast transient ,response with few external components. The low impedance internal MOSFET ,supports high efficiency operation with wide input voltage range from 4.3V to ,18V. The proprietary circuit of the RT7285/A enables to support all ceramic ,capacitors. The output voltage can be adjusted between 0.6V and 8V.
