LT1614
Inverting 600kHz Switching Regulator
DESCRIPTIO
The LT®1614 is a fixed frequency, inverting mode switching reglator that operates from an input voltage as low as 1V. Utilizing a low noise topology, the LT1614 can generate a negative output down to – 24V from a 1V to 5V input. Fixed frequency switching ensures a clean output free from low frequency noise.
