TI SWIFT step-down regulator simplifies industrial power design

Texas Instruments Inc. introduced a synchronous 50-mA, 60-V SWIFT step-down regulator with high efficiency and low noise performance in a solution size of 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 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. 

Key highlights:

• 65-V transient protection for specification overhead; wide temperature operation (-40° to 150°C); 90-percent efficiency at 24 Vin, 5 Vout at 150 kHz
• TPS54062 can be synchronized to a clock via fixed frequency
• 89-µA operating current with a shutdown current of 1.7 µA
• 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

Pricing: Suggested resale pricing is $1.50 in 1,000-unit quantities.

Availability: In volume now from TI and authorized distributors in an 8-pin, 3-mm x 5-mm MSOP PowerPad package.
