Below figures show some examples of USB Type-C applications and related Richtek power management ICs : Figure 2. Figure 2 shows a typical USB-PD adapter charging solution, where the adapter power supply provides an adjustable USB bus voltage 5V, 9V, 15V or 20V based on the request of th...
PD 快充协议发展至今，已经更新到 PD 3.0 规范，相较于 PD 1.0、PD 2.0，它包含了一 PPS（Programmable Power Supply）可编程电源，可以根据实现电压电流调节的供电规范，从而以适应高电压低电流和低电压大电流的两种快充模式。由此，带有 PPS 的 PD 3.0 规范几乎涵盖了市面上主流的快充模式，包括高通的 QC...
自从USB PD第3版以来,外接电源单元和用电设备可以更动态地调整电压和电流。为了实现这一点,双方必须支持可选的标准扩展PPS(Programmable Power Supply可编程电源供应协议)。 设备可以向充电器请求电压和电流,这些请求可以稍微偏离规定的电源配置文件:这可以加快充电过程,但也可以确保在充电期间电池受到的压力较小,或者根...

USB-IF协会于2021年9月30日-10月1日期间在美国西雅图成功举办了USB开发者大会,宣布了新的认证 USB Type-C线缆额定功率logo,经过认证的 USB Type-C 线缆将显示logo支持近期发布的 USB Power Delivery (USB PD) 3.1规范定义的 60W 或 240W 功率。
新的USB PD 3.0协议还支持可编程电源(Programmable Power Supply, PPS) 协议,容许对总线电压和电流进行精确调节,而电压则可以低于5V。利用这样的协议,使用可调的总线电压对电池进行直接充电的高效直充系统就成为可能,这时的总线电压可以低达3V。标准的Type-C电缆额定的负载能力是3A,当更高的电流出现时,含有电子标签的...
Input and Output Power The USB-C to USB-A PD Adapter requires 20V DC for operation. It can be connected to either the DC Jack or Terminal Blocks (but not simultaneously). The included 20V/3.25A (65W) standard power supply must be connected to the DC Jack. ...
