U-122 A New Family of Integrated Circuits Controls Resonant Mode Power
PDF, 272 Kb, Archivo publicado: sept 5, 1999
This application note introduces the UC3861-8 family of ICs which are optimized for the control of zero-current-switched and zero-voltage-switched quasi-resonant converters. Differences among members of this device family result from the various combinations of UVLO thresholds and output options. The one-shot pulse steering logic is configured to program either on time for ZCS systems (UC1865-186
