UCC15241-Q1 is an automotive qualified high isolation voltage DC/DC power module designed to provide power to IGBT or SiC gate drivers. The UCC15241-Q1 integrates a transformer and DC/DC controller with a proprietary architecture to achieve high efficiency 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 UCC15241-Q1 provides up to 2.5W (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.
