Texas Instruments' 60-V, 2.2-MHz DC/DC converter reduces overall solution size and cost in automotive designs

Power management IC provides 65-microamp quiescent current

May 5, 2009

DALLAS (May 5, 2009) - Texas Instruments Incorporated (TI) (NYSE:TXN) today introduced an automotive-qualified DC/DC step-down converter that offers a leading combination of high voltage up to 60 V, a switching frequency up to 2.2-MHz and ultra-low quiescent current of 65 microamp in a small, monolithic package. The first in a family of automotive-qualified DC/DC controllers and converters, the TPS54362-Q1 converts an unregulated input voltage to a fixed lower output voltage to power automotive applications, such as infotainment, navigation systems and power supply for electronic control units. The TPS54362-Q1 allows designers to reduce overall solution size, cost and design complexity when compared to discrete solutions. For product details see: www.ti.com/tps54362-q1-pr.

Key features and benefits

  • Support for transients up to 60 V and a wide input voltage range of 3.6 V to 48 V protects the system from spikes.
  • Frequency up to 2.2-MHz allows for smaller external components, saving valuable board space and reducing overall solution cost.
  • Ultra-low quiescent current of 65 microamp and standby mode reduces drain from the vehicle battery, resulting in longer battery life.
  • Integrated voltage supervisor helps monitor system performance.

Availability and pricing

The TPS54362-Q1 is available now in a HTSSOP-20 package. The TPS54362-Q1 is priced at $2.75 in quantities of 1,000.
