UCC34141 is a reinforced isolation, high working voltage, DC/DC power module designed to provide power to SiC and IGBT isolated gate drivers. TI’s proprietary integrated transformer and advanced control architectures achieve high power density, low noise, and a low system bill of materials. This device is capable of delivering 1.5W typical output power at 85°C ambient temperature. The highly accurate dual-output voltages, easily set by resistor dividers, enables 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. The device is operational from 5.5V to 20V VIN, and can withstand VIN overvoltage transients up to 28V.

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