TI's 50-mA, 60-V Synchronous Step-down Converter Simplifies Industrial Power Design

High-performance DC/DC converter with integrated FETs provides 90-percent power efficiency, transient protection in smallest solution

DALLAS -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a synchronous 50-mA, 60-V SWIFT(TM) step-down regulator with high efficiency and low noise performance in a solution size of only 125 mm2. The TPS54062 integrates both the high-side and low-side power MOSFETs, providing efficient power conversion and transient protection to noise-sensitive industrial automation and sensor control, smart meter, telecom, computing and consumer designs.

The new 50-mA, 60-V SWIFT converter can withstand high-voltage transients up to 65 V, while maintaining high efficiency across the load. For higher voltage transient protection at 50 mA, TI recently introduced its new TPS7A4001 50-mA, 100-V LDO, which achieves an extremely fast settling time of less than 500 nanoseconds for a 50-V transient event.

The TPS54062 also supports a variety of TI embedded processor applications, including Stellaris® ARM® Cortex(TM)-M MCUs, C5000(TM) ultra-low power DSPs and ultra-low power MSP430(TM) 16-bit MCU-based applications, such as smart meter, building automation and security systems.

Key features and benefits of the TPS54062:

-- High efficiency and performance: 65-V transient protection for specification overhead; wide temperature operation (-40 degrees to 150 degrees C); 90-percent efficiency at 24 Vin, 5 Vout at 150 kHz.
-- Excellent noise performance: TPS54062 can be synchronized to a clock via fixed frequency.
-- Low-power operation: 89-uA operating current with a shutdown current of only 1.7 uA.
-- Smallest solution size: switching frequency range of 100 to 400 kHz and small MSOP package with integrated high and low-side FETs result in a 20 mm2 board space savings compared to competitive solutions.

Availability and pricing

The TPS54062 is available in volume now from TI and authorized distributors in an 8-pin, 3-mm x 5-mm MSOP PowerPad(TM) package. Suggested resale pricing is $1.50 in 1,000-unit quantities.
