The RTQ7880-QT is a USB Type-C Power Delivery (USB-C PD) and PWM buck-boost controller with highly integrated by the specific functions and the flexibility for USB PD provider applications. The IC has embedded an ARM Cortex<sup>TM</sup>-M0 MCU so as to handle 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 properly even when the MCU is not activated. The RTQ7880-QT hereby offers an excellent USB PD solution for a USB-PD Provider application with minimal external components and simple PCB layout.
