RT5712D

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

General Description

Features

 Efficiency Up to 95%

 R_DSON100mΩ HS / 70mΩ LS

 V_INRange 2.7V to 6V

 V_REF0.6V with ±1.5% Accuracy

The RT5712D is a high efficiency synchronous

step-down DC-DC converter. Its input voltage range is

from 2.7V to 6V and provides an adjustable regulated

output voltage from 0.6V to 3.4V while delivering up to

2A of output current.

 CMCOT™ Control Loop Design for Best

Transient Response, Robust Loop Stability with

Low-ESR (MLCC) C_OUT

The internal synchronous low on-resistance power

switches increase efficiency and eliminate the need for

an external Schottky diode. The Current Mode

Constant-On-time (CMCOT) operation with internal

compensation allows the transient response to be

optimized over a wide range of loads and output

capacitors.

 Fixed Soft-Start 1.2ms

 Cycle-by-Cycle Over-Current Protection

 Input Under-Voltage Lockout

 Output Under-Voltage Protection (UVP Hiccup)

 Thermal Shutdown Protection

Marking Information

Applications

 STB, Cable Modem, & xDSL Platforms

 LCD TV Power Supply & Metering Platforms

 General Purpose Point of Load (POL)
