TI introduces 30-A, 15-V synchronous buck converter with 90-percent efficiency
High-performance voltage regulator with integrated FETs provides highest efficiency, fastest transient protection in new PowerStack(TM) package
(PresseBox) - 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(TM) simulation model and evaluation module visit: www.ti.com/tps53355-preu.
The TPS53355 30-A regulator uses a D-CAP(TM) 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(TM) 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.
