The RT7880B is a USB Type-C Power Delivery (USB-C PD) and PWM buck controller with highly integrated functions and flexibility for USB PD provider applications. The IC has an embedded ARM CortexTM-M0 MCU, which handles various functions of communication protocol, smart control of the PWM converter, firmware-based protections, and customized functions. The IC features hardware-based protections, such as inductor peak current limit, VBUS over-voltage protection (VBUS OVP), VO under-voltage protection (VO UVP), and VCONN current limit protection, so that the protections have faster responses and can still function even when the MCU is not activated. The RT7880B can offer an excellent USB PD solution for a USB-PD Provider application with few external components and simple PCB layout.
