RT6218A/B

18V, 2A, ACOT^TMStep-Down Converter in 8 Pin TSOT-23

General Description

Features

 Input Supply Voltage Range : 4.5V to 18V

 2A Converter With Built-in 120m/65m Low

RDS(ON) Power FETs

The RT6218A/B is

simple, easy-to-use, 2A

synchronous step-down DC-DC converter with an input

supply voltage range of 4.5V to 18V. The device

integrates low R_DS(ON)power MOSFETs to achieve

high efficiency in a SOT23 package and build-in

accurate reference voltage (0.765V by product

options).

 Advanced Constant On-Time (ACOT^TM) Control

for Ultrafast Transient Response

 Fixed Switching Frequency : 650kHz (SOT23-8)

 Optional for Operation Modes :

 Automatically Power Saving Mode (PSM)

The RT6218A/B adopts Advanced Constant On-Time

(ACOT^TM) control architecture to provide an ultrafast

transient response with few external components and

to operate in nearly constant switching frequency over

the line, load, and output voltage range. The RT6218A

operates in automatic PSM that maintains high

efficiency during light load operation. RT6218B

operates in Forced PWM that helps meet tight voltage

regulation accuracy requirements.

(RT6218A)

 Forced PWM Mode (RT6218B)

 Optimized for Low-ESR Ceramic Output

Capacitors

 1.5% High-Accuracy Feedback Reference

Voltage

 Output Voltage Range : up to 6.5V

 Externally Adjustable Soft-Start

 Monotonic Start-Up for Pre-biased Outputs

 Both HS/LS FETs Protection for Robust Over

Current Protection

The RT6218A/B senses both FETs current for a robust

over-current

protection. The

device features

cycle-by-cycle current limit protection and prevent the

device from the catastrophic damage in output short

circuit, over current or inductor saturation. The

RT6218A/B series offers programmable start-up by

connecting a capacitor at external SS pin. The device

also includes input under-voltage lockout, output

under-voltage protection, and over-temperature

protection (thermal shutdown) to provide safe and

smooth operation in all operating conditions. The

RT6218A/B are offered in TSOT-23-8(FC) package.

 Input Under-Voltage Lockout (UVLO)

 Output Under-Voltage Protection (UVP) with

Hiccup Mode

 Over-Temperature Protection (OTP) (Thermal

Shutdown)

 Enable Control

 Power Good Indication

 RoHS Compliant and Halogen Free

 Available in TSOT-23-8 Package

Applications

 Set-Top Boxes

 LCD TVs
