4n35 optoisolator

Abstract: Pulse Transformer 5024 Application Note 13 52kHz LM2574/5/6 Family Design Guide by Kevin Lynn Introduction Micrel's LM257x family of BiCMOS simple buck voltage regulators feature faster rise/fall time, faster response to fault conditions, and improved efficiency at light loads. Description The LM257x switching regulator is basically a PWM (pulse width modulation) controller IC with a fixed gain error ampli fier, a 52kHz , LM257x family does not support external compensation.) Specifi cally, this avoids the right half-plane

Abstract: D e s ig n S o l u t io n 1 2 0 0 k H z S w itching R egulator R educes B oard S pace by Brian Huffman The Micrel MIC4574, MIC4575 and MIC4576 are enhanced versions of the popular LM257x family of 52kHz, step-down (buck), switching regulators. They feature a 200kHz switch ing frequency that reduces the inductor size by a factor of four, freeing up precious board space, and allows conversion from 12V to 5V/1A in under one square inch of board space. The MIC457x series operates from input voltages -
