DALLAS, Feb. 11, 2020 /PRNewswire/ -- Texas
Instruments (TI) (Nasdaq: TXN) today introduced the first
integrated circuit (IC) developed with a new proprietary integrated
transformer technology: a 500-mW high-efficiency isolated DC/DC
converter with the industry's lowest electromagnetic interference
(EMI), the UCC12050. Its 2.65-mm height enables designers to reduce
their solution volume by as much as 80% compared to discrete
solutions and 60% compared to power modules – with twice the
efficiency of competing devices. Built for industrial performance,
the UCC12050's 5-kVrms reinforced isolation and 1.2-kVrms working
voltage protect against high-voltage spikes in systems such as
industrial transport, grid infrastructure and medical equipment.
For more information, see www.ti.com/UCC12050-pr.
TI's breakthrough integrated transformer technology enables
high-density isolated DC/DC power conversion, while maintaining low
EMI. The single-package, surface-mount architecture gives designers
an easy-to-use, low-profile IC that reduces the bill of materials
(BOM), and efficiently operates across a wide temperature range. An
EMI-optimized, low capacitance transformer and quiet control scheme
streamline EMI compliance while providing a reliable solution with
options for reinforced or basic isolation. Download the white
paper, "Power Through the Isolation Barrier: The Landscape of
Isolated DC/DC Bias Power Supplies" to learn more about this new
family of reinforced isolated DC/DC bias supplies.
TI will demonstrate the UCC12050 in booth No. 1001 at the
Applied Power Electronics Conference (APEC) in New Orleans, Louisiana, March 15-19, 2020.
Key features and benefits of the UCC12050
- Small size, increased power density: Available in
a 16-pin small-outline integrated circuit (SOIC) package measuring
10.3 mm by 10.3 mm by 2.65 mm, the UCC12050 offers 60% efficiency –
twice that of competing devices of similar size – and twice the
power density of comparative isolated power modules. Delivering 0.5
W in the new architecture improves reliability, enables a small BOM
and simplifies board layout.
- Ultra-low EMI: The UCC12050's integrated transformer
with very low primary-to-secondary capacitance is optimized for EMI
performance, and its quiet control scheme makes it easier for
engineers to have their designs pass Comité International Spécial
des Perturbations Radioélectriques (CISPR) 32 Class B EMI tests,
with margin, on a two-layer printed circuit board. The solution
also eliminates external filter components such as low-dropout
regulators and ferrite beads normally required to meet EMI
certification, which significantly reduces component selection and
design time.
- Reinforced isolation, wide temperature range: The
UCC12050's reinforced isolation with 8-mm creepage and clearance is
used for protection and robustness against ground potential
differences. Its high efficiency and extended -40°C to 125°C
operating temperature range deliver more power in extreme
conditions. Read the technical article, "Isolation 101: How to find
the right isolation solution for your application," to learn how
reinforced isolation and the UCC12050, in particular, can help save
time, effort, space and possibly cost over other isolated bias
supply solutions.
This new high-density isolated power converter, the latest
industry-leading device in TI's power-management portfolio, offers
small size and ease of use for any industrial application requiring
isolation. Additionally, the new UCC12040 provides all of the
same benefits with 3-kVrms basic isolation.
Package, availability and pricing
The UCC12050 and
UCC12040 are available in volume production from TI and authorized
distributors in a 16-pin, 10.3-mm-by-10.3-mm-by-2.65-mm SOIC
package. Pricing starts at US$3.90
and US$3.15, respectively, in
1,000-unit quantities. Engineers can evaluate this product with the
UCC12050EVM-022 evaluation module, available on TI.com for
US$99.
