LT1949EMS8#PBF Datasheet PDF - Linear Technology

●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.

● Low-battery detector stays active in shutdown

● Pin-for-pin compatible with the LT1317B

● 600kHz Fixed frequency operation

● 410mV at 800mA Low VCESAT switch
