Preface
Bull has launched a 140W peak series fast charging socket, which has three new national standard five-hole jacks and has a 3C1A fast charging interface, which can meet the needs of office desktops using laptops, connecting monitors, charging mobile phones and other peripherals. The socket has a physical switch that allows for global power supply control without the need for frequent plug plugging and unplugging. The USB-C1 port supports 140W fast charging, USB-C2 supports 100W fast charging, USB-C3 supports 30W fast charging, and the USB-A port supports 22.5W fast charging.
When the charging head network disassembled this charger, it was found that it has built-in Yingji core IP2738U, IP2726, IP6550 three chips, which are detailed for you below.
Bull 140W Mountain Peak Fast Charging Socket
The package contains a two-piece set: the Bull 140W Peak Series GaN Fast Charging Socket and a 1.5m PD3.1 240W data cable.
This product continues the same design of the Bull Mountain Peak series fast charging socket, with black coating throughout, the surface of the flame-retardant shell uses a frosted texture process, the texture design is matched with a metallic decorative ring, and the front bottom has an atmosphere indicator, which highlights the grade and is more fashionable at the same time.
One of the major features of the socket is that the bottom of the fuselage is "chopped" off, so that the fuselage is tilted 30° upwards, bringing a more reasonable plugging and unplugging angle and improving the comfort of use. The corners of the fuselage are rounded, and there is a set of 3+2 new national standard combination sockets on the top surface and one side. On the other side, there is also a set of 3+2 new national standard combination sockets, which can supply power to three high-power electrical appliances at the same time.
After a brief look at the appearance, the charging head network continues to ask you to introduce its built-in Yingjixin protocol chip IP2738U, IP2726 and synchronous rectification step-down controller IP6550 three high-performance chips.
英集芯协议芯片IP2738U
The protocol chip of USB-C1 and C2 ports adopts Yingjixin IP2738U, which is a protocol chip that supports multiple USB interfaces, supports dual-port 18-140W fast charging applications, has independent feedback control, and has independent USB PD control, which is equivalent to two IP2736 integrated into one chip, and the fast charging specifications are the same as IP2736. It supports USB PD3.1 28V EPR gear, UFCS fusion fast charging, and PD3.0/PPS and other rich and comprehensive fast charging protocols, and the compatibility is very good.
Yingjixin IP2738U built-in four independent NMOS drivers, which can be used for output control of multiple interfaces, control multiple VBUS switches for output port switching and parallel control of two power supplies, and support dual independent over-current, over-voltage and short-circuit protection to ensure safe use.
Yingjixin protocol chip IP2726
USB-C3 and USB-A port protocol chips are from Yingjixin, model IP2726, which is a very widely used protocol chip. Yingjixin IP2726 is a fast charging IC that integrates multiple protocols and is used for USB output port.
IP2726 supports Type-C DFP, PD2.0/3.0, PPS, QC4+, QC2.0/3.0, FCP, AFC, SCP, MTK PE+, Apple2.4A, BC1.2 and Samsung 2A. With high integration and rich functions, only a few peripheral components are required for application, effectively reducing the size of the overall solution and reducing the BOM cost.
Yingjixin synchronous rectifier step-down controller IP6550
The synchronous rectification buck controller for the step-down output is from Yingjixin, the model is IP6550, which is a synchronous step-down controller that supports 36V input, with a built-in NMOS tube drive and two external MOS transistors for efficient synchronous rectification and step-down. The IP6550 regulates the output voltage via the feedback pin. The switching frequency is 135KHz, the input terminal withstand voltage is 48V, and the built-in perfect protection function is complete. Yingjixin IP6550 adopts a 3*3mm QFN16 package, which can realize the simplified synchronous step-down conversion circuit design.
The IP6550 can be used in car chargers, multi-port adapters, smart sockets, USB-C socket strips, and dashcam applications. The synchronous rectification step-down has high conversion efficiency, high output current can be used for multi-port 5V output, and can be used with PD protocol chip to achieve a wide range of voltage regulation, which meets the application of USB PD3.1.
Summary of the charging head network
Charging head network learned that Shenzhen Yingjixin Technology Co., Ltd. is a high-performance, high-quality digital-analog hybrid chip design company, the main business is the research and development and sales of power management chips, fast charging protocol chips. Yingjixin's chip products have the characteristics of high integration, high customizability, high cost performance and low substitutability, which can shorten the research and development cycle of customers' finished product solutions, simplify the production process of customers' products, and improve product yield and reliability, so as to help customers optimize costs and meet diversified needs.
Bull's mountain peak fast charging socket uses Yingji core IP2738U, IP2726 and IP6550 to complete multi-port fast charging output. Among them, IP2726 supports PD3.0/PPS, QC, FCP, AFC, SCP and other mainstream fast charging protocols, with rich functions, meeting dual-port applications and strong reliability. In addition to the above protocols, the IP2738U also supports PD3.1 and UFCS protocols, and has a built-in four-way NMOS driver, which is minimalist in the periphery, which is equivalent to two built-in IP2736 and supports dual-port 18-140W fast charging applications. The IP6550 integrates dual NMOS drivers, supports soft-start, line compensation, and protection functions, effectively simplifying the design of synchronous step-down circuits. The combination of these three chips can meet the use of multi-port fast charging scenarios such as PD adapters, table chargers, and smart plug-in boards.
