Renesas Electronics Announces Industry’s First USB-C™ Combo Buck-Boost Battery Charger for Mobile Computing Systems

TOKYO, Japan ― Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today introduced the industry’s first USB-C™ buck-boost battery charger to support both Narrow Voltage Direct Charging (NVDC) and Hybrid Power Buck-Boost (HPBB) charging for notebooks, ultrabooks, tablets, and power banks using the reversible USB Type-C™ connector cable. Through firmware control, the ISL9241 can switch between NVDC and HPBB modes, providing a low-cost and small solution size capable of efficiently processing a full range of power levels. It leverages Renesas’ advanced R3™ modulation technology for superior light-load efficiency and ultra-fast transient response to extend battery run-time. The charger’s reconfigurable internal registers allow the use of a smaller inductor for HPBB mode to achieve higher efficiencies across multiple power levels.
