UCC14341-Q1 is a high isolation voltage DC/DC module designed to provide power to IGBT or SiC gate drivers. The module 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 higher system efficiency without over-stressing the power device gate.

The fully integrated module with on-chip device protection requires a minimum of external components, and 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.
