ABSTRACT :
A new family of integrated circuits is introduced. Devices from this family implement the necessary architecture to control a broad range of resonant mode converters.
Key features in the areas of switch timing, fault management, and soft-start technique arc unique to this family.
Individual devices arc customized to handle off-line or DC to DC, single-ended or dual-switch, zero-voltage-or-current-switched configurations. Specific application to three different resonant mode converters is mentioned.

Présentation :
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 (UC1865-1868), or off time for ZVS applications (UC1861-1864).
Key features in switch timing, fault management, and soft-start technique are unique to this family.
Individual devices arc customized to handle off-line or DC to DC, single-ended or dual-switch, zero-voltage-or-current-switched configurations.
Specific application to three different resonant mode converters is mentioned.
