3 Description

UCC14141-Q1 is an automotive qualified high

isolation voltage DC/DC power module designed

to provide power to IGBT or SiC gate drivers.

The UCC14141-Q1 integrates a transformer and

DC/DC controller with a proprietary architecture to

achieve high density with very low emissions. The

high-accuracy output voltages provide better channel

enhancement for higher system efficiency without

over-stressing the power device gate. The input

voltage of UCC14141-Q1 supports both wide LiFePO4

battery voltage of electric vehicle (8 V-18 V) and

regulated 12-V rail (10.8 V-13.2 V), with different

output power.

The fully integrated module with on-chip device

protection requires a minimum of external

components, and provides extra features such as

input under-voltage lockout, over-voltage lockout,

output voltage power-good comparators, overtemperature

shutdown, soft-start time-out, adjustable

isolated positive and negative output voltage, an

enable pin, and an open-drain output power-good pin.
