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

The UCC35131-Q1 is an automotive qualified high isolation voltage DC/DC power

module designed to provide power to IGBT, SiC, Si and GaN isolated gate drivers and UIR

Sensors. 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 2.0W 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 and GaN devices. 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

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.
