3 Description

UCC15241-Q1 is an automotive qualified high

isolation voltage DC/DC power module designed to

provide power to IGBT or SiC gate drivers. The

UCC15241-Q1 integrates a transformer and DC/DC

controller with a proprietary architecture to achieve

high efficiency with very low emissions. The highaccuracy

output voltages provide better channel

enhancement for higher system efficiency without

over-stressing the power device gate.

The UCC15241-Q1 provides up to 2.5W (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.
