Problem
Device manufacturers face challenges delivering fast, efficient charging in compact form factors while meeting stringent safety and regulatory requirements. Traditional charging solutions often require multiple discrete components, leading to larger PCB footprints, higher BOM costs, and limited integration of wireless power capabilities.
Solution
NuVolta provides highly integrated power management ICs that combine wireless and wired fast‑charging functions, synchronous rectification, programmable low‑dropout regulators, and on‑chip microcontrollers. Their ICs support up to 80 W wireless power transfer and over 100 W wired charging with efficiencies exceeding 90 %, reducing component count and board area. Built‑in protection features (UVLO, OVP, OCP, OTP, SCP) and bidirectional communication (ASK/FSK) ensure safe operation and enable smart power‑management protocols such as Qi2, PD 3.1, QC 3.0, and FOD detection. The devices are offered in compact QFN packages and include integrated ADCs, high‑efficiency full‑bridge FET drivers, and programmable LDO/Buck converters, allowing OEMs to design slimmer, more reliable chargers for smartphones, wearables, automotive, and industrial applications.
Target Audience
Primary customers are OEMs and ODMs developing smartphones, tablets, wearables, power banks, automotive infotainment systems, and industrial equipment that require high‑efficiency, space‑constrained charging solutions.
