Supertex's New CL8800 & CL8801 Sequential Drivers for Long Strings of LEDs Directly from AC Mains to Replace FL-Tubes
Supertex's New CL8800 & CL8801 Sequential Drivers for Long Strings of LEDs Directly from AC Mains to Replace FL-Tubes Supertex, a recognized leader in high voltage analog and mixed signal integrated circuits (ICs), today introduced CL8800 and CL8801, sequential, linear LED drivers designed to drive long strings of low cost, low current LEDs in solid-state replacements for fluorescent tubes, incandescent bulbs and CFL bulbs. Both ICs minimize driver circuit component counts, requiring just four or six resistors and a diode bridge in addition to the IC. Two to four additional components in the circuit provide transient protection, and neither capacitors nor magnetic components are required. Because the ICs are multi-stage linear current regulators, there are no high frequency switching currents and, thus, no need for a front-end EMI filter. CL8800 is intended for 230VAC input, while CL8801 is for 120VAC input. Luminous efficiencies of greater than 115lm/W are achievable with both ICs. Read more »
