Isolated DC-DC module provides power to IGBT or SiC gate drivers

The Texas Instruments UCC14240-Q1 is an automotive-qualified high isolation voltage DC-DC power module created to supply power to IGBT or SiC gate drivers. The device combines a transformer and DC-DC controller with a proprietary architecture to provide high efficiency with very low emissions. The high-accuracy output voltages offer better channel enhancement for higher system efficiency without over-stressing the power device gate.

The device supplies up to 2W (typical) of isolated output power at high efficiency. Needing a minimum of external components and incorporating on-chip device protection, the module offers extra features such as input undervoltage lockout, overvoltage lockout, output voltage power-good comparators, overtemperature shutdown, adjustable isolated positive and negative output voltage, an enable pin, soft-start time-out, and an open-drain output power-good pin.
