Power density enabled by 180-kHz maximum switching frequency
Current sense emulation greatly reduces power losses associated with traditional current sensing circuitry
Integration of GaN, driver, OCP, and OTP simplifies design, reduces BOM count, and increases system robustness
USB-C output enables full system-level evaluation for end-equipments like adapters, notebook chargers, USB wall outlets
