Murata's LED Boost ICs are ultra-high efficiency DC-DC converter solution with integrated programmable current sinks that drive up to six/eight strings of LEDs. The LED Boost integrates all MOSFETs and their control and driver circuitry. With the proprietary architecture, the LED boosts provide the highest efficiency (up to 96%) possible in a compact WLCSP or QFN package. The unique two-stage architecture enables a small and low-profile solution size aligned to the needs of the latest mobile products.
