LTC3528-2 - 2MHz Synchronous Step-Up DC/DC Converter

General Description

The LTC®3528-2 is a synchronous, fixed frequency step-up DC/DC converter with output disconnect.

High efficiency synchronous rectification, in addition to a 700mV startup voltage and operation down to 500mV once started, provides longer run-time for single or multiple cell batterypowered products.

Key Features

  • n Delivers 3.3V at 200mA from a Single Alkaline/ NiMH Cell or 3.3V at 400mA from Two Cells n VIN Start-Up Voltage: 700mV n 0.50V to 5.5V Input Range n 1.6V to 5.25V VOUT Range n Up to 94% Efficiency n Output Disconnect n 2MHz Fixed Frequency Operation n VIN > VOUT Operation n Integrated Soft-Start n Current Mode Control with Internal Compensation n Burst Mode® Operation with 12µA Quiescent Current n Internal Synchronous Rectifier n Logic Controlled Shutdown:.
