137W Holdup Converter for Storage Server Reference Design
Description
PMP20818 is a holdup reference design that uses the LM3481 non-synchronous boost and LM5141-Q1 synchronous buck controllers. When the 12V input supply is available: the buck converter is disabled: and the boost converter charges a capacitive holdup bank. In the event of a power outage: the boost converter is disabled: and the buck converter is enabled to holdup the 12V input rail for 15ms with a load of 12.5A.
