EC3292B

18V/2A High Efficiency Synchronous Rectified

Step-Down DC/DC Converter

Features

General Description

◆ Input Voltage Supply Range from 4.5V to 18V

The EC3292B is a high efficiency synchronous step-down

DC/DC converter series with 2A continuous output current

supplied. Included on the substrate with the features listed

is a high performance trans-conductance error amplifier

that provides tight voltage regulation and accuracy under

transient conditions. A built-in Under Voltage Lockout

(UVLO) circuit is provided to prevent start-up until the input

voltage reaches to 4.5V. In addition, it features over-

current protection and thermal shutdown. To improve the

light load efficiency, it is designed as the power saving

mode (PSM) to minimize the switching loss by reducing

the switching frequency. The EC3292B is available in

SOT23-6L package.

◆ Power Saving Mode (PSM) during the light Load

Operation

◆ High Efficiency up to 95%

◆ Adjustable Output Voltage from 0.6V to 12V

◆ 2A Continuous Output Current

◆ 500KHz Constant Frequency Operation

◆ Current Mode Operation

◆ Programmable Soft-Start

◆ Over-temperature Protection

◆ Over-current Protection

◆ Input Under Voltage Lockout (UVLO)

◆ 10µA Shutdown Current

◆ SOT23-6L Package

◆ RoHS Compliant (100% Green Available)

Application

◆ Data comm. DSL CPE Graphics Cards

◆ Set-Top-Box, DVD

◆ Telecomm Equipments

◆ DC-DC Regulator Modules

◆ LCD Monitor and LCD TV

◆ Servers/Networking

◆ DSP and FPGA Power Supply
