Datasheet Details
The Supertex LR745 is a high input voltage SMPS startup circuit.
The LR745 is ideally suited for use with industry standard low voltage PWM ICs having start thresholds of 13.9 - 18.0V.
It allows the PWM ICs to be operated from rectified 120 or 240VAC lines, and eliminates the use of power resistors o
