3 Description
The UCC28610 brings a new level of performance
and reliability to the AC and DC consumer power
supply solution.
A PWM modulation algorithm varies both the
switching frequency and primary current while
maintaining discontinuous or transition mode
operation over the entire operating range. Combined
with a cascoded architecture, these innovations result
in efficiency, reliability, and system cost
improvements over a conventional flyback
architecture.
The UCC28610 offers a predictable maximum power
threshold and a timed response to an overload,
allowing safe handling of surge power requirements.
Overload fault response is user-programmed for retry
or latch-off mode. Additional protection features
include output overvoltage detection, programmable
maximum on-time, and thermal shutdown.
