The RTQ7883B-QT is a highly integrated functions USB Type-C Power Delivery (USBC PD) with internal 2 switch PWM buck converter up to 3A output current and duty cycle 99% for low dropout operation. The IC has an embedded ARM CortexTM-M0 MCU, which handles various functions of communication protocol, smart control of the PWM converter, DP/DM USB2.0 switch, firmware-based protections, and customized functions. The IC features hardware-based protections, such as inductor peak current limit, VBUS overvoltage protection (VBUS OVP) and VO undervoltage protection (VO UVP), so that the protections have faster responses and can still function even when the MCU is not activated. The RTQ7883B-QT can offer an excellent USB PD solution for a USB-PD Provider application with few external components and simple PCB layout.
The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 105°C.
