UCC14131-Q1 is an automotive qualified high isolation voltage DC/DC power module designed to provide power to GaN, IGBT, SiC, or Si gate drivers. The UCC14131-Q1 integrates a transformer and DC/DC controller with a proprietary architecture to achieve high efficiency with very low emissions. It can provide an isolated 12-V output from a 12-V regulated input for driving GaN and Si MOSFETs; and an isolated 15-V or 18-V output from a 15-V regulated input to bias the driver circuit for SiC MOSFET or IGBTs. The high-accuracy provides better channel enhancement for higher system efficiency without over-stressing the power device gate.
The UCC14131-Q1 provides up to 1.5W (typical) of isolated output power at high efficiency. Requiring a minimum of external components and including on-chip device protection, the module provides extra features such as input undervoltage lockout, overvoltage 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.
