RT6222A/B

2.5A, 18V, 500kHzACOT^TMSynchronousStep-Down Converter

General Description

Features

^4.3V to 18V Input Voltage Range

The RT6222A/B is a synchronous step-down converter

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

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 RT6222A/B enables to support all ceramic capacitors.

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

^2.5A 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

^Hiccup Mode Under-Voltage Protection

^Thermal Shutdown
