RT8097A

6V, 2A, 1MHz, CMCOT Synchronous Step-Down Converter

General Description

Features

 Efficiency Up to 95%

The RT8097A is a simple, easy-to-use, 2A synchronous

step-down DC-DC converter with an input supply voltage

range of 2.7V to 6V. The device build-in an accurate 0.6V

(typ.) reference voltage and integrates low R_DS(ON)power

MOSFETs to achieve high efficiency in a SOT-23-5 and

SOT-23-6 packages.

 2A Converter With Built-In 100m/70m Low

R_DS(ON)Power FETs

 Input Supply Voltage Range : 2.7V to 6V

 Output Voltage Range : 0.6V to 3.4V

 Current Mode Constant On-Time (CMCOT)

Control

The RT8097A adopts Current Mode Constant On-Time

(CMCOT) 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 RT8097A

operates in automatic PSM that maintains high efficiency

during light load operation.

 Ultrafast Transient Response

 No Needs For External Compensations

 Optimized for Low-ESR Ceramic Output

Capacitors

 0.6V 1.5% High-Accuracy Feedback Reference

Voltage

The RT8097A senses low-side FETs current for a robust

over-current protection. It features cycle-by-cycle current

limit protection and prevent the device from the

catastrophic damage in output short circuit, over current or

inductor saturation. An internally adjustable soft-start

function prevents inrush current during start-up. 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 RT8097A is offered in a

SOT-23-5 and SOT-23-6 packages.

 LS FETs Protection for Robust Over-Current

Protection

 Power Saving in Light Load

 Fixed Switching Frequency : 1MHz (typ.)

 Internally Soft-Start Function

 Monotonic Start-Up for Pre-Biased Output

 Input Under-Voltage Lockout (UVLO)

 Output Under-Voltage Protection (UVP) with

Hiccup Mode

 Power Good Indication in SOT-23-6 Package

 Enable Control

 Available In SOT-23-5 and SOT-23-6 Packages

Applications

 STB, Cable Modem, & xDSL Platforms

 LCD TV Power Supply & Metering Platforms

 General Purpose Point of Load (POL)
