RT7235/36/39/40

5A, 18V, 650kHz, ACOT^TMSynchronous Step-Down Converter

General Description

Features

^ACOT^TMMode Enables Fast Transient Response

^4.5V to 18V Input Voltage Range

^5A Output Current

The RT7235/36/39/40 is a synchronous step-down DC/

DC converter withAdvanced Constant On-Time (ACOT^TM)

mode control. It achieves high power density to deliver up

to 5Aoutput current from a 4.5V to 18V input supply. The

proprietary ACOT^TMmode 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, RT7235/36/39/40 keeps an excellent constant

switching frequency under line and load variation and the

integrated synchronous power switches with theACOT^TM

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 RT7235/36/39/40, output Under

Voltage Protection (UVP) / Over Voltage Protection (OVP)

for RT7235/36. When the UVP/OVP is triggered, the device

will enter latch mode for TSSOP-14 (Exposed Pad), and

hiccup mode for WDFN-10L 3x3.

^35mΩ Internal Low Site N-MOSFET

^Advanced Constant On-Time Control

^Support All Ceramic Capacitors

^Up to 95% Efficiency

^650kHz Switching Frequency at all Load Current

(RT7235, RT7239)

^Discontinuous Operating Mode at Light Load

(RT7236, RT7240)

^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

Applications

 Industrial and Commercial Low Power Systems

 Computer Peripherals

 LCDMonitors and TVs

The RT7235/36 are available in TSSOP-14 (Exposed Pad)

and WDFN-10L 3x3 packages, and the RT7235 is operated

in forced continuous conduction mode.

 Green Electronics/Appliances

 Point of Load Regulation for High-Performance DSPs,

FPGAs, and ASICs

The RT7239/40 are available in the SOP-8 (Exposed Pad)

package, and the RT7239 is operated in forced continuous

conduction mode.
