iKF is an electronic light fashion luxury design brand, iKF-Fun Pro is a true wireless earbuds that support active noise cancellation. It has a high-value design, fashionable and sophisticated. In terms of functional configuration, iKF-Fun Pro is equipped with iKF full-range noise reduction technology, which provides a maximum depth noise reduction effect of -49dB. The 13mm dynamic driver, tuned by iKF's professional team, delivers surging sound quality and rich sound details.
Recently, I love audio network dismantled the iKF-Fun Pro true wireless earbuds, and found that its charging case integrates IP6818 multi-functional power management SoC from INJOINIC, with a high degree of integration, and a single chip can provide a complete power solution for the TWS Bluetooth earphone charging case.
In terms of functional configuration, the iKF-Fun Pro true wireless earbuds use Bluetooth V5.4 connection, and also support iKF intelligent dual connection technology, supporting 38ms low-latency gaming mode. In terms of battery life, the earbuds provide a single 6-hour and a combined 32-hour battery life. iKF's App enables intelligent interaction and can find headphones, private alarm clocks, customized EQ, DIY touch, sleep mode, timer shutdown and other extended functions.
After a detailed dismantling of the iKF-Fun Pro true wireless earbuds, it was found that the charging case of the iKF-Fun Pro true wireless earbuds has built-in LED indicators, lithium-ion battery packs, multi-function power management SoCs, overvoltage protection ICs and other components. The earbuds integrate a 13mm speaker unit, a 40mAh battery, a lithium battery protection IC, a MEMS microphone, a Bluetooth audio SoC, a laminated ceramic inductor and other components. Among them, the multi-functional power management SoC of the charging case is Yingjixin IP6818, which can provide a complete power solution for the charging compartment of TWS Bluetooth earphones.
INJOINIC IP6818 multi-functional power management SoC, integrated Qi wireless charging and receiving, 5V boost converter, lithium battery charging management, battery level indication, etc., the integration is very high, a single chip can provide a complete power solution for the TWS Bluetooth earphone charging case.
The high level of integration and rich functions of IP6818 make it require only a few peripheral components for application, and effectively reduce the size of the overall solution and reduce the BOM cost. IP6818 built-in MCU, can be flexibly customized 4/3/2/1 LED power display; Built-in 12-bit ADC to accurately calculate battery level.
