DC/DC converter cuts cost, space in automotive apps

Texas Instruments Inc. has released an automotive-qualified DC/DC step-down converter that offers a combination of high voltage up to 60V, a switching frequency up to 2MHz, and ultralow quiescent current of 65?A 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. In addition, the TPS54362-Q1 allows designers to reduce overall solution size, cost and design complexity when compared to discrete solutions.

The converter features a wide input voltage range of 3.6 V to 48 V that protects the system. Its 2MHz frequency allows for smaller size external components, saving valuable board space and reducing overall solution cost. In addition, the ultralow quiescent current and standby mode of the device ensure less battery drain from the vehicle battery, resulting in longer battery life. The TPS54362-Q1 also has an integrated voltage supervisor to help monitor system performance.

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