Design

RT2810A/B

10A, 18V, 500kHz, ACOT^TMSynchronous Step-Down Converter

General Description

Features

^4.5V to 18V Input Voltage Range

The RT2810A/B is a synchronous step-down converter

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

TheACOT^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 4.5V to 18V. The proprietary circuit

of the RT2810A/B enables to support all ceramic

capacitors. The output voltage can be adjustable between

0.7V and 8V. The soft-start is adjustable by an external

capacitor.

^10A Output Current

^12mΩ Internal High-Side N-MOSFET and 5.4mΩ

Internal Low-Side N-MOSFET

^Advanced Constant On-Time Control

^Fast Transient Response

^Support All Ceramic Capacitors

^Up to 95% Efficiency

^Adjustable Switching Frequency from 300kHz to

700kHz

^Adjustable Output Voltage from 0.7V to 8V

^Adjustable Soft-Start
