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

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.
