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 LiFePO 4 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, over-temperature shutdown, soft-start time-out, adjustable isolated positive and negative output voltage, an enable pin, and an open-drain output power-good pin.
