LTC3499B - 750mA Synchronous Step-Up DC/DC Converters

Download the LTC3499B datasheet PDF. This datasheet also covers the LTC3499 variant, as both devices belong to the same 750ma synchronous step-up dc/dc converters family and are provided as variant models within a single manufacturer datasheet.

Description

The LTC®3499/LTC3499B are synchronous, fixed frequency step-up DC/DC power converters with integrated reverse battery protection that protect and disconnect the devices and load when the battery polarity is reversed while delivering high efficiency in a small (3mm × 3mm) DFN package.

Features

  • n Reverse-Battery Protection for DC/DC Converter and Load n High Efficiency: Up to 94% n Generates 5V at 175mA from a 1.8V Input n Operates from 1.8V to 5.5V Input Supply n 2V to 6V Adjustable Output Voltage n Inrush Current Controlled During Start-Up n Output Disconnnect in Shutdown n Low Noise 1.2MHz PWM Operation n Tiny External Components n Automatic Burst Mode® Operation (LTC3499) n Continuous Switching at Light Loads (LTC3499B) n Overvoltage Protection n 8-Lead (3mm × 3mm × 0.75mm) DFN and.
