LT1242CS8 - Brand New AC DC Converters, Offline Switchers
-
Description
The LT1242CS8 is an 8-pin, fixed frequency, current mode, pulse width modulator. It is an improved version of the industry standard UC1842 series, offering both improved speed and lower quiescent current. This model is optimized for off-line and DC/DC converter applications and features a temperature-compensated reference, high-gain error amplifier, current sensing comparator, and a high-current totem pole output stage designed for driving power MOSFETs. The start-up current has been reduced to less than 250µA.
