3 Description

UCC14130-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 UCC14130-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 UCC14130-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.
