Introduction
General Product Information
The RT7285C is a synchronous step-down converter with Advanced Constant On-
Time (ACOT™) mode control.
The
ACOT™
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 ci
rcuit
of the RT7285C enables to support all ceramic capacitors. The output voltage can be adjusted between 0.6V and 8V.
The RT7285C also provides output under voltage protection and thermal shutdown protection. The low current
(<4
μA) shutdown mode provides output disconnection, enabling easy power management in battery-powered
systems. The RT7285C is available in TSOT-23-6 package.
