- DN-33 Optocoupler Feedback Drive Techniques Using the UC3901 and UC3903PDF, 45 Kb, Archivo publicado: sept 5, 1999
A variety of low-cost supervisory ICs contain the required building blocks for the more demanding optocoupler feedback drive applications. Initially developed to address other specific power supply tasks several control ICs excel in the role as precision optocoupler control and drivers. This design note describes a basic optocoupler driver circuit and also a more advanced optocoupler drive circ - Optimizing Resistor Dividers at a Comparator (Rev.
