The HIGHWAY09A is not sold through major distributors like Mouser or DigiKey. Instead, it is found on specialized electronic component marketplaces: : Most commonly available in a PDIP16 (16-pin
): A 4.7 µH to 10 µH inductor with a saturation current rating at least 30% higher than the maximum system current draw is recommended. Output Capacitor ( COUTcap C sub cap O cap U cap T end-sub Instead, it is found on specialized electronic component
: Power supply and ground pins for stable operation.
If the LED string is shorted, the sense resistor sees full current. The IC will attempt to regulate, but the voltage across the pass transistor becomes V_IN (e.g., 14.4V). Power dissipation spikes, triggering OTP within milliseconds. The IC enters a "hiccup" mode (on/off cycling) until the short is removed.
The negative/inverting channel of the differential communication highway. Pairs with BUS_P to form a noise-resilient transmission line.
