This section will cover the selection of the series capacitor for the TPS54A20

Targeting the Test and Measurement application, this section includes many topics relevant to designing with SAR ADC devices.

This section presents the buck-boost dc-dc converter as an effective and efficient solution for the wide vin automotive battery rail. The advantages compared to pre-boost and two stage solutions are presented. Also contains an overview of buck-boost converter and controller offerings convering various current and power levels.

With rapidly expanding electronic content in latest generation of cars, there is an ever increasing need for power conversion from the car battery rail. The 12-V battery rail is subject to a variety of transients. This presents a unique challenge in terms of the power architecture for off-battery systems. This presentation introduces the different types of transients that occur in automotive battery rails, the causes of those transients, and the standards and specifications defining the test conditions for those transients.

This section presents the different methods of protecting the electronic loads connected to the automotive battery rail in the event of accidental reverse battery connection. The methods covered include:

• Schottky diode
• PFET + discretes
• Smart diode + NFET

Why should you understand power management?

For many engineers, layout for EMI mitigation is a black art. It may seem like the slightest adjustment could be the difference between passing or failing CISPR standards. Because of this, some power designers may shy away from using devices with switching elements as a guaranteed way to avoid the headache of reducing emissions. But this may be trading one problem for another, as switching devices generally have better efficiency and thermal performance.

Efficiently addressing EMI starts at the device selection stage. On-silicon technologies like spread spectrum or unique packaging approaches like HotRod™ QFN can help reduce EMI before we even begin the discussion of component layout and filtering.
