The SiP280X family includes six high-speed, low power consumption, BiCMOS Current Mode Controllers. These integrated circuits contain all of the control and drive functions required for off-line and dc-to-dc current-mode switching power supplies. Their advanced architecture enables the implementation of full-featured designs with minimal external parts count.
The SiP280X family controllers are available in both standard and lead (Pb)-free, SO-8 and TSSOP-8 packages, and are rated for operation over the industrial temperature range of -40 to 85 .
Currents are positive into, negative out of the specificed terminal. Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolutemaximumrating conditions for extended periods may affect device reliability.
