UCC14240-Q1 is a high isolation voltage DC/DC module designed to provide power to IGBT or SiC gate drivers. The high-accuracy output voltages provide better channel enhancement for higher system efficiency without over-stressing the power device gate. The module integrates a transformer and DC/DC controller with a proprietary architecture to achieve high efficiency with very low emissions.

The UCC14240-Q1 provides > 1.5 W (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 under-voltage lockout, over-voltage lockout, output voltage powergood comparators, over-temperature shutdown, soft-start timing, adjustable isolated positive and negative output voltage, an enable pin, and an open-drain output powergood pin.
