TI udvider power-porteføljen

Texas Instruments lancerer 50mA, 100-V LDO og 12A, 60V step-down controller til brug i industrisystemer (in english).

Texas Instruments (TI) has expanded its power management portfolio with two new step-down regulators with wide input voltages and high-voltage protection. The new 100-V LDO and 60-V DC/DC controller can withstand high-voltage transients, while maintaining high efficiency - providing peace of mind to designers of low- to mid-current, high-voltage telecom and industrial designs, such as motor control, HVAC relay, smart meters and automotive after-market applications.

The TPS7A4001 50-mA LDO has according to TI the industry’s widest input voltage tolerance with an input voltage 7 V to 100 V, and achieves an extremely fast settling time of less than 500 nanoseconds for a 50-V transient event. The device, which comes in a tiny 8-pin, thermally enhanced 3-mm x 5-mm MSOP package, has a low quiescent current of 25 uA and ensures output accuracy in a noisy environment. www.ti.com/tps7a4001-preu.  


The TPS40170 synchronous step-down DC/DC controller offers a high degree of performance, efficiency and reliability, including voltage-mode control with input voltage feed-forward compensation, while supporting input voltages from 4.5 V to 60 V and output currents up to 12 A.

The controller protects against voltage spikes up to 62 V, offers a fast FET on-time of 75 ns and shutdown current of 1.0 uA. The TPS40170’s unique bi-directional synchronization feature eliminates system beat and EMI noise and reduces input capacitance by up to 50 percent, saving board space. The device comes in a 3.5-mm x 4.5-mm QFN, and has samples and evaluation modules available at: www.ti.com/tps40170-pr.   

SWIFT converters with integrated FETs

In addition to the TPS40170 controller, TI provides a range of SWIFT monolithic switchers with integrated FETs to simplify design in lower current 60-V applications. The 2.5-A TPS54260, 1.5-A TPS54160 and 500-mA TPS54060 converters provide up to 95 percent efficiency to 12-, 24- and 48-V industrial and commercial designs and GSM/GPRS modules used in smart meters, fleet management and security systems. All three SWIFT converters are pin-compatible for design flexibility. For more information, visit: www.ti.com/swift-pr.
