With the full transition of the iPhone 15 series to the USB-C port, the integration trend of electronic device interfaces is becoming more and more obvious. Nowadays, whether it is a smartphone, a smartwatch or a variety of state-of-the-art electronic devices, it is common to use the USB-C interface for power supply. The popularity of USB-C fast charging continues to expand and has become the industry standard for efficient charging and data transfer.
Against this backdrop, many power bank manufacturers are also actively adapting to market changes, equipping power banks with a single USB-A port and multiple USB-C ports, which can not only provide efficient fast charging for many new devices, but also ensure compatibility with more traditional devices.
Through dismantling, the charging head network learned about the latest mass production of Yingjixin's 22The 5W power bank is fully integrated with SOC IP5365, supports up to 3 TypeC PD channels, and is compatible with a variety of mainstream fast charging protocols on the market, especially the latest UFCS national standard fast charging protocol.
Yingjixin IP5365 is for a single-string battery power bank, supporting 225W discharge power, the biggest highlight is that it supports two Type-C port input and output and one TypeC port output, a total of three fast charging outputs, which is perfectly suitable for the power bank scheme of C port + C line + Lightning fast charging line.
IP5365 not only supports mainstream fast charging protocols on the market, but also supports UFC converged fast charging, which is more compatible and adaptable. IP5365 can support digital tube display without MCU, built-in switching power MOS and path MOS, and can realize charging and discharging functions with a single inductor.
IP5365 built-in switch and VBUS switch, integrated 14-bit ADC, support 1-4 lamp LED power display, support 88 or 188 digital tube power display, support automatic power on/off, integrated input over-voltage, under-voltage protection, output over-current, over-voltage, short-circuit protection, battery overcharge, over-discharge and over-current protection, chip built-in over-temperature protection, and support external NTC for battery temperature protection.
Compared with the traditional solution, the application schematic diagram of Yingjixin IP5365 integrates the VBUS switch tubes of each interface inside the chip, and the peripheral components are very simple, greatly simplifying the layout and materials.
IP5365 adopts QFN48 6x6mm 04pitch package is suitable for portable electronic devices such as mobile power banks, mobile phones, and tablets.
IP5365 is the successor to IP5365 and IP5355 22After the 5W explosive mobile power chip, the latest multi-port fast charging mobile power chip was launched, which supports a variety of fast charging protocols, including PD30, pps and UFCS, QC30. AFC, SCP, etc., support the maximum charging current of 5A battery, and support two C-port input and output and one A-C port output, either interface can realize the fast charging function, and support digital tube display.
The IP5365 has a variety of built-in protection mechanisms, including over-voltage, under-voltage, over-current, over-voltage, short-circuit, over-charge, over-discharge, and over-current protection, as well as over-temperature protection, and supports external NTC for battery temperature protection. The application schematic simplifies the peripheral components, greatly simplifies the layout and materials, and is packaged in a QFN48 6x6mm 04pitch is suitable for portable electronic devices such as mobile power banks, mobile phones, and tablets.
