TI Introduces 50mA, 60V Synchronous Step-Down Converter
Texas Instruments Inc. (TI) introduced a synchronous 50mA, 60V SWIFT™ 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 50mA, 60V SWIFT converter can withstand high-voltage transients up to 65V, while maintaining high efficiency across the load. For higher voltage transient protection at 50mA, TI recently introduced its new TPS7A4001 50mA, 100V LDO, which achieves an extremely fast settling time of less than 500 nanoseconds for a 50V transient event.
The TPS54062 also supports a variety of TI embedded processor applications, including Stellaris® ARM® Cortex®-M MCUs, C5000® ultra-low power DSPs and ultra-low power MSP430® 16-bit MCU-based applications, such as smart meter, building automation and security systems.
Key features and benefits of the TPS54062 include: 65V transient protection for specification overhead; wide temperature operation (-40 to 150°C); 90-percent efficiency at 24Vin, 5Vout at 150 kHz; 89µA operating current with a shutdown current of only 1.7µA; and switching frequency range of 100 to 400 kHz and small MSOP package with integrated high and low-side FETs result in a 20mm² board space savings compared to competitive solutions.
The TPS54062 is available in volume in an 8-pin, 3 x 5mm MSOP PowerPad™ package. Suggested resale pricing is $1.50 in 1,000-unit quantities.
