LT1245IS8 - Brand New Linear Technology DC DC Switching Controllers
-
Description
The LT1245IS8 is an electronic component model in the category of DC DC Switching Controllers. It is an 8-pin, fixed frequency, current mode, pulse width modulator that is an improved plug compatible version of the industry-standard UC1842 series. The LT1245IS8 features improved speed, lower quiescent current, and is optimized for off-line and DC/DC converter applications. With a temperature-compensated reference, high-gain error amplifier, current sensing comparator, and a high current totem pole output stage, it is ideally suited for driving power MOSFETs. The start-up current has been reduced to less than 250µA.
