Automotive, 2W, 5.5V-to-20V VIN, regulated 5kVRMS isolated DC-DC module with integrated transformer

The UCC35341-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 2W

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 8V to 20V VIN, and

can withstand VIN overvoltage transients up to 28V.

The integrated protection features, fault-report

Power-Good 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.
