Supertex HV9919Using a buck topology, Supertex’s HV9919 SSLD uses a hysteretic control function to maintain its output current between a fixed minimum and maximum level at all times. The PWM controller performs in solid-state lighting applications, such as industrial, architectural, signage, or decorative lighting; indicator or emergency lighting; and as a general-purpose, constant-current source. The component offers programmable dimming frequency via a single capacitor and a 8-lead DFN package. Pricing is $0.55 each in 1,000 quantities.
