LT1308A - DC/DC Converters

General Description

The LT®1308A/LT1308B are micropower, fixed frequency step-up DC/DC converters that operate over a 1V to 10V input voltage range.

They are improved versions of the LT1308 and are recommended for use in new designs.

Key Features

  • n 5V at 1A from a Single Li-Ion Cell n 5V at 800mA in SEPIC Mode from Four NiCd Cells n Fixed Frequency Operation: 600kHz n Boost Converter Outputs up to 34V n Starts into Heavy Loads n Automatic Burst Mode™ Operation at Light Load (LT1308A) n Continuous Switching at Light Loads (LT1308B) n Low VCESAT Switch: 300mV at 2A n Pin-for-Pin Upgrade Compatible with LT1308 n Lower Quiescent Current in Shutdown: 1μA (Max) n Improved Accuracy Low-Battery Detector Reference: 200mV ± 2% n Available in 8-Lea.
