3 Description

UCC14340-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, overtemperature

shutdown, soft-start timing, adjustable

isolated positive and negative output voltage, an

enable pin, and an open-drain output powergood pin.
