DN-42A Design Considerations for Transitioning from UC3842 to the New UCC3802

Texas Instruments

Published Date: 09/05/1999

Description

The UCC3802 offers numerous advantages that allow the power supply design engineer to meet requirements for lower power for battery-operated equipment higher switching frequencies for reduced magnetics size higher levels of circuit integration for improved reliability and lower cost. The UCC3802 family of devices is pin-out compatible with the UC3842 and UC3842A families; however it is not plu
