UCC2813QDR-3Q1 General Description

Incorporating the UCC2813QDR-3Q1 into your designs allows for simplified PWM control in power supply applications. The device's BiCMOS technology combines the advantages of both bipolar and CMOS technologies, offering high speed and low power consumption. The internal soft start and current-sense input blanking streamline the setup process, while the 1.5V reference voltage provides stable operation across varying loads. Whether used in automotive or industrial settings, this device ensures reliable performance under harsh conditions

Received the product in less than a month. I used it for making a handwired keyboard and the 32U4 is working flawlessly. Used QMK to flash on the firmware and it's working good.Probably will order more for future keyboard builds.
