Overview
NCP1910 High Performance Combo Controller for ATX Power Supplies 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 awa...
