Applications - TWS Bluetooth Earphone Charging Box - Lithium Battery Portable Device 3. Description IP6818 is a multi-functional power management SOC for total solution on TWS Bluetooth Earphone Charging Box. It integrates with Qi wireless power receiver, 5V-boost converter, lithium battery charging management and battery level indicators. IP6818 is highly integrated with abundant functions, which makes the total solution size minimized and BOM costed down. The synchronous 5V-boost system of IP6818 provides rated 300m A output current with conversion efficiency up to 93%. DC-DC converter operates at 1.5MHz, and can support low-cost...
