FUNCTION DESCRIPTION
Type M51996AP and M51996AFP are especially designed for
off-line primary PWM control IC of switching mode power supply
to get DC voltage from AC power supply.
Using this IC,smart SMPS can be realized with reasonable
cost and compact size as the number of external electric
parts can be reduced and also parts can be replaced by
reasonable one.
In the following circuit diagram,MOS-FIT is used for output
transistor,however bipolar transistor can be replaced with no
problem.
