RT6202A/B

5A, 18V, 650kHz, ACOT^®SynchronousStep-Down Converter

General Description

Features

^ACOT Mode Enables Fast Transient Response

The RT6202A/B is a synchronous step-down DC/DC

^4.5V to 18V Input Voltage Range

^5A Output Current

converter withAdvanced Constant On-Time (ACOT ) mode

control. It achieves high power density to deliver up to 5A

output current from a 4.5V to 18V input supply. The

^35mΩ Internal Low Side N-MOSFET

^Advanced Constant On-Time Control

^Support All Ceramic Capacitors

^Up to 95% Efficiency

proprietary ACOT mode offers an optimal transient

response over a wide range of loads and all kinds of ceramic

capacitors, which allows the device to adopt very low ESR

output capacitor for ensuring performance stabilization. In

addition, RT6202A/B keeps an excellent constant

switching frequency under line and load variation and the

^650kHz Switching Frequency at all Load Current

(RT6202B)

^Discontinuous Operating Mode at Light Load

(RT6202A)

integrated synchronous power switches with theACOT

mode operation provides high efficiency in whole output

current load range. Cycle-by-cycle current limit provides

an accurate protection by a valley detection of low side

MOSFET and external soft-start setting eliminates input

current surge during startup. Protection functions include

thermal shutdown for RT6202A/B.

^Adjustable Output Voltage from 0.765V to 8V

 Adjustable Soft-Start

 Cycle-by-Cycle Current Limit

 Input Under Voltage Lockout

 Thermal Shutdown

 RoHS Compliant and Halogen Free

The RT6202A/B are available in the SOP-8 (Exposed Pad)

package.

Applications

 Industrial and Commercial Low Power Systems

 Computer Peripherals

Pin Configuration

 LCDMonitors and TVs

(TOP VIEW)

 Green Electronics/Appliances

 Point of Load Regulation for High-Performance DSPs,

FPGAs, andASICs
