Product Overview

The LT1949EMS8#PBF is a fixed-frequency step-up DC-to-DC Converter with a 1A/0.5R internal switch. Capable of generating 10V at 175mA from a 3.3V input, the LT1949 is ideal for generating bias voltages for large screen LCD panels. Constant frequency 600kHz operation results in a low noise output that is easy to filter and the 30V switch rating allows output voltage up to 28V using a single inductor. An external compensation pin gives the user flexibility in optimizing loop compensation, allowing small low ESR ceramic capacitors to be used at the output. The LT1949 includes a low-battery detector that stays alive when the device goes into shutdown. Quiescent current in shutdown is 25µA, while operating current is 4.5mA.
  • Operates with VIN as low as 1.5V
  • Low-battery detector stays active in shutdown
  • Pin-for-pin compatible with the LT1317B
  • 600kHz Fixed frequency operation
  • 410mV at 800mA Low VCESAT switch
