The UCC34141-Q1 is an automotive qualified high isolation voltage DC/DC power module designed to provide power to SiC and IGBT isolated gate drivers. Its proprietary integrated transformer, flip-chip package, and advanced control architectures achieve high power density, low noise, and lowest system BOM. This device is capable of delivering 1.5W typical output power at 85oC ambient temperature. The highly accurate dual-output voltages, easily set by resistor dividers, enable low on-resistance, fast and reliable switching for SiC/IGBT. The low-latency feedback control reduces the output capacitance for fast load transient and supports dynamic voltage programming. The wide input voltage and adjustable VIN UVLO supports both wide battery voltage of electric vehicles and regulated input rails. It is operational from 5.5V to 20V VIN, and can withstand VIN overvoltage transient up to 28V.

The integrated protection features, fault-report PG pin, and enable function increase system robustness and save external components. The SOIC package with 8.2mm creepage and clearance distance ensures high isolation capability.
