TI unveils industry’s

highest power density 12-V,

10-A, 10-MHz DC/DC

converter

Ultra-small SWIFT™ step-down

converter features unique topology

to achieve four times higher current

density

Texas Instruments (TI) (NASDAQ:

TXN) today introduced the

industry’s first 12-V, 10-A, 10-MHz

series-capacitor buck converter

that achieves more than 50 A/cm3

in current density, which is four

times higher than any other 12 V

power management component or

solution available today. The unique

topology of the TPS54A20 SWIFT

synchronous DC/DC converter

enables high-frequency operation

at up to 5 MHz per phase without

special magnetics or compound

semiconductors, which designers

can use for 8-V to 14-V input and

10-A output applications. By using

the step-down converter together

with TI’s WEBENCH® Power

Design tool, engineers can get

their space- and height-constrained

point-of-load (POL) telecom and

networking power-supply designs to

market faster. For more information,

samples and an evaluation module,

visit

www.ti.com/tps54a20-pr-eu.

The TPS54A20 features a unique

two-phase, series-capacitor DC/

DC buck topology that merges a

switched-capacitor circuit with a

multiphase buck converter. This

capacitive conversion technology

enables efficient, high-frequency

operation and measures as much

as seven times smaller than

conventional converters. For a

quick introduction, watch the video

“How to decrease inductor size in a

10-A DC/DC converter design” and

read the white paper, “Breakthrough

power

delivery

for

space-

constrained applications.” Read the

application note “Introduction to the

Series Capacitor Buck Converter”

that analyzes the technology and

presents example results for a 12-V

input, 1.2-V/10-A output application

demonstrating

higher

peak

efficiency than a conventional buck

converter, while operating at four

times higher switching frequency.

TPS54A20 key features and

benefits

Tiny solution: Small HotRod™

quad flat no-lead (QFN) packaging

and inexpensive, tiny 2- to 5-MHz

inductors enable a 131-mm2

solution size that consumes 50

percent less area than similar 500-

kHz DC/DC converter designs.

Read the blog post, “No small

matter: How to reduce voltage

regulator size.”

Low profile: Measuring less than

2 mm in height, the reduced size,

weight and bill of materials (BOM)

allows placement of tiny 10-A

voltage regulators on the back
