Texas Instruments UCC14131-Q1 Isolated DC/DC Modules
Texas Instruments UCC14131-Q1 Isolated DC/DC Modules are 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 accomplish high efficiency with very low emissions.The TI UCC14131-Q1 can deliver an isolated 12V output from a 12V regulated input for driving GaN and Si MOSFETs and an isolated 15V or 18V output from a 15V regulated input to bias the driver circuit for SiC MOSFET or IGBTs. The UCC14131-Q1 modules supply high accuracy with better channel enhancement for higher system efficiency without over-stressing the power device gate.
