It delivers up to 10 W in flyback, buck, or buck-boost topologies, making it a compact choice for auxiliary supplies and appliance power stages. Switching at 60 kHz with a 70% duty cycle ceiling, the part operates from a Vcc supply range of 11.5 V to 23.5 V and includes a 13 V start-up threshold. Fault protection covers current limiting and over-temperature — no external sense resistor needed for cycle-by-cycle current limit. ## Multi-topology flexibility for BOM consolidation Supporting buck, buck-boost, and flyback topologies from the same IC means one line item can serve multiple PSU designs — a 10 W flyback for a smart-meter supply and a 5 W buck for an appliance standby rail, for example. The output isolation is configurable as either isolated or non-isolated, depending on the transformer or inductor choice. The 800 V breakdown voltage gives headroom for universal mains (85–265 VAC) applications without derating the MOSFET.
