RT7880
USB Type-C PD and PWM Buck-Boost Controller with AnyPowerTM and PDsafeTM Features
General Description
The RT7880 is a USB Type-C Power Delivery (USB-C PD) and PWM buck-boost 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.
