the multiplier. Line current dead zone is minimized with
low bias voltage at the current input to the multiplier.
The LT1509 provides many protection features including
peak current limiting and overvoltage protection. Imple-
mented with a very high speed process, the LT1509 can be
operated at frequencies as high as 300kHz.
DESCRIPTIO
N
U
By using fixed high frequency PWM current averaging
without the need for slope compensation, the LT1509
achieves far lower line current distortion with a smaller
magnetic element than systems that use either peak
current detection, or zero current switching approach, in
both continuous and discontinuous modes of operation.
The LT1509 also provides filtering capability to reject line
switching noise which can cause instability when fed into
