Automotive switching regulators get input-transient-voltage protection

Focus:

The addition of a simple input protection circuit stops transients up to 50 V, permitting use of high-frequency (3 MHz) switching regulators in automotive applications

What you’ll learn:

• How to protect general-purpose switching regulators against voltage transients in automotive applications
• How to shrink buck regulator designs in automotive applications
• How to protect a switching regulator against alternator load-dump in automotive applications
