DALLAS, Sept. 15, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced a synchronous 30-A
step-down regulator with integrated MOSFETs that achieves
90-percent power efficiency and fast transient response in a small
5-mm x 6-mm PowerStack QFN package. The TPS53355 converter delivers
high performance to low-output voltage, high-current applications
that demand increased power density, such as notebook computers,
embedded computers, servers, storage and telecommunication systems.
For samples, SwitcherPro™ simulation model and evaluation module
visit: www.ti.com/tps53355-pr.
The TPS53355 30-A regulator uses a D-CAP™ mode control feature
to achieve a transient response of up to 2 A/µs, which is
20-percent faster than other solutions that use current or voltage
mode control. The D-CAP mode control also minimizes the use of
external components and requires no loop compensation.
Key features and benefits of the TPS53355:
- High efficiency and performance: input voltage range up to 15
V; 90-percent efficiency at 30-A, 12 Vin, 1.5 Vout at 500 kHz.
- Accurate power delivery: 1 percent voltage regulation
accuracy.
- Light-load efficiency: Eco-Mode™ auto-skip mode operation.
- Smallest solution size: selectable switching frequency range of
250 kHz to 1 MHz and small QFN package with integrated high and
low-side FETs result in a 20-percent smaller solution than
competitive products.
Availability and pricing
The TPS53355 is available in volume now from TI and authorized
distributors in a 22-pin, 5-mm x 6-mm QFN PowerStack package, a
unique package technology that helps reduce board space, while
achieving excellent thermal performance, higher current capability
and efficiency. Suggested resale pricing is $4.65 in 1,000-unit quantities.
