3 Description

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.
