Texas Instruments (TI) announced the launch of a
synchronous 50-mA, 60-V 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 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-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.
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.
