QCY’s latest flagship, the MeloBuds N70, is pushing the limits of TWS endurance. At its heart is the Injoinic IP5529, an all-in-one SoC that combines a 32-bit MCU with high-efficiency charging and boosting. By handling 1A charging and 800mA boosting with up to 93% efficiency, this chip allows QCY to cut down on extra components, saving both space and cost while maintaining top-tier power performance.
The "secret sauce" here is Follow Charging. Unlike standard chargers, the IP5529 can adjust voltage in tiny 10mV increments to match the earbud's needs perfectly. This reduces wasted energy and boosts total battery life by up to 20%. This tech is exactly how QCY managed to hit a massive 50-hour total runtime without making the case bulky, keeping that sleek, pebble-like aesthetic users love.
Audio fans aren't left out either. The N70 uses a high-tech MEMS + Dynamic dual-driver setup for lightning-fast transients and deep bass. It’s backed by Hybrid ANC with six modes and a 6-mic array for crystal-clear calls. It’s a rare combination of audiophile-grade hardware managed by a professional-grade power system.
With a standby current of just 15µA, the IP5529 is a benchmark for low-power design. Its flexible QFN28 packaging gives engineers the freedom to customize firmware for unique features. For QCY, the IP5529 isn't just a component—it’s the engine that delivers their promise of "fast, low-power, and long-lasting" audio to the global market.
