Boost regulators provide the necessary high voltages to drive multiple LEDs in series, guaranteeing accurate LED current matching.
ST offers both single- and multi-channel high-efficiency boost LED drivers featuring a wide dimming range, low noise and small footprint. They also embed protection functions such as overvoltage and overcurrent protection, thermal shutdown and LED-array protection.
