Housed in a SO−24WB package, the NCP1910 combines
a state-of-the-art circuitry aimed to powering next generation of ATX
or flat TVs converters. With a 65 or 100 kHz Continuous Conduction
Mode Power Factor Controller and a LLC controller hosting
a high-voltage driver, the NCP1910 is ready to power 85+ types of
offline power supplies. To satisfy stringent efficiency considerations,
the PFC circuit implements an adjustable frequency fold back to
reduce switching losses as the load is going light. To cope with all the
signal sequencing required by the ATX and flat TVs specifications, the
controller includes several dedicated pins enabling handshake
between the secondary and the primary sides. These signals include
a power-good line but also a control pin which turns the controller on
and off via an opto coupler. Safety-wise, a second OVP input offers the
necessary redundancy in case the main feedback network would drift
away. Finally, a fast fault input immediately reacts in presence of an
over current condition by triggering an auto-recovery soft-start sequence.
