Power Semiconductor – LED Boost

Murata Power Semiconductor achieves an innovative power conversion with proprietary virtually loss-less charge pump technology.
It’s unique power architecture enables to use small inductors as well as low voltage FETs for whole power rail to provide system level benefits as shown in the following.

  • Ultra-high efficiency with small footprint and low profile
  • Low input/output ripple
  • Low EMI performance
  • High reliablity

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.

Murata’s Unique Two-stage Architecture for Boost conversion

A highly flexible multi-stage architecture comprising a patented “pipeline” stage switched-capacitor network (charge pump) combined with boost stage.
