Patented LED driver from Supertex delivers high current accuracy
Because of the patented, novel scheme of current control it employs, the HV9861A doesn’t produce a peak-to-average error like many LED driver ICs, and therefore, it greatly improves the accuracy and line and load regulation of the LED current. The IC provides typical current accuracy of +/-3% and requires no loop compensation or highside current sensing because of its proprietary control scheme. The internally regulated voltage (Vdd) for HV9861A is 7.5V.
HV9861A is available in SOIC-8 and SOIC-16 packages (HV9861ALG-G & HV9861ANG-G, respectively) and are pin-compatible with Supertex’s HV9910B and HV9961 LED drivers. The parts are RoHS compliant. Samples are available from stock. Lead-time for production quantities for the HV9861A is 4-6 weeks ARO. Pricing is US$0.81 for the HV9861ALG-G, US$0.89 for the HV9861ANG-G, in 1K quantities.
The device is available through distributor Retronic (https://www.retronic.de/en/HomeEN.htm )
