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. The device contains a lowbattery detector with a 200mV reference and shuts down
to less than 10μA. No load quiescent current of the LT1614
is 1mA and the internal NPN power switch handles a
500mA current with a voltage drop of just 295mV.
High frequency switching enables the use of small inductors and capacitors. Ceramic capacitors can be used in
many applications, eliminating the need for bulky tantalum types.
The LT1614 is available in 8-lead MSOP or SO packages.
