RT7295D
3A, 18V, 500kHz ACOT^TM Synchronous Step-Down Converter
General Description
The RT7295D is a synchronous step-down converter with
Advanced Constant On-Time (ACOT^TM) mode control. The
ACOT^TM 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 RT7295D enables to support all ceramic capacitors.
The output voltage can be adjusted between 0.6V and 8V.
