3 Description

UCC12040 is a DC/DC power module with 3-kV_RMS

basic isolation rating designed to provide efficient,

isolated power to isolated circuits that require a

bias supply with a well-regulated output voltage. The

device integrates a transformer and DC/DC controller

with a proprietary architecture to provide 500 mW

(typical) of isolated power with low EMI.

•

– Isolation rating: 3 kV_RMS

– Surge capability: 6.5 kV_PK

– Working voltage: 850 V_RMS

– CMTI (typical): ±100 V/ns

Short circuit recovery

Thermal shutdown

16-pin wide-body SOIC package with > 8-mm

creepage and clearance

Extended temperature range: –40°C to 125°C

Safety-related certifications:

– 5657-V_PKbasic isolation per DIN V VDE V

0884-11:2017- 01

The UCC12040 integrates protection features for

increased system robustness. The device also has an

enable pin, synchronization capability, and regulated

5-V or 3.3-V output options with headroom. The

UCC12040 is a low-profile, miniaturized solution

offered in a wide-body SOIC package with 2.65-mm

height.
