RT5753

3A, 1.2MHz, 6V Synchronous Step-Down Converter

In WDFN-8L 2x2

General Description

Features

 Input Voltage Range from 2.5V to 6V

The RT5753 is a simple, easy-to-use, 3A synchronous

step-downDC-DC converter with an input supply voltage

range from 2.5V to 6V. The device builds in an accurate

0.6V reference voltage and integrates low R_DS(ON)power

MOSFETs to achieve high efficiency in WDFN-8L 2x2 and

WDFN-8SL 2x2 packages.

 Integrated 100mΩ and 70mΩ FETs

 100% Duty Cycle for Lowest Dropout

 Internal Reference Voltage with 1% Accuracy

 1.2MHz Typical Switching Frequency

 Power Saving Mode for Light Loads (RT5753A/C/E/F)

 Advanced Constant On-Time (ACOT ) Control

The RT5753 adoptsAdvanced Constant On-Time (ACOT )

 Internal Soft-Start (1.5ms/750μs)

 Enable Control Input

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 RT5753A/C/E/F operates

in automatic PSM that maintains high efficiency during

light load operation. The RT5753B/D operates in Forced

PWM that helps to meet tight voltage regulation accuracy

requirements.

 Power Good Indicator

 Both FETs Overcurrent Protection

 Negative Overcurrent Protection (RT5753B/D)

 Input Undervoltage Lockout Protection

 Output Undervoltage Protection

 Over-Temperature Protection

 RoHS Compliant and Halogen Free

The RT5753 senses both FETs current for a robust

overcurrent protection. The device features cycle-by-cycle

current limit protection which prevents the device from

the catastrophic damage in output short circuit, over current

or inductor saturation.Abuilt-in soft-start function prevents

inrush current during start-up. The device also includes

input undervoltage lockout, output undervoltage protection,

overvoltage protection (RT5753AL/BL/CL/DL/EL/FL) and

over-temperature protection to provide safe and smooth

operation in all operating conditions.

Applications

 Mobile Phones and HandheldDevices

 STB, Cable Modem, and xDSL Platforms

 WLANASIC Power / Storage (SSDand HDD)

 General Purpose for POL LV Buck Converters
