RT7285D

1.5A, 18V, 500kHzACOT^TMSynchronousStep-Down Converter

General Description

Features

^4.3V to 18V Input Voltage Range

The RT7285D is a synchronous step-down converter with

Advanced Constant On-Time (ACOT^TM) mode control. The

ACOT^TMprovides 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 RT7285D enables to support all ceramic capacitors.

The output voltage can be adjusted between 0.6V and 8V.

^1.5A Output Current

^Advanced Constant On-Time Control

^Fast Transient Response

^Support All Ceramic Capacitors

^Up to 95% Efficiency

^500kHz Switching Frequency

^Adjustable Output Voltage from 0.6V to 8V

^Cycle-by-Cycle Current Limit

^Input Under-Voltage Lockout

^Thermal Shutdown
