PMP7919, Power Solution for an Automotive Voltage Stabilizer. The PMP7919 is a 2-phase synchronous boost converter that can take a minimum 5.5V input and put out 11.5V or higher at 15A. It is used in the Voltage Quality Module in a start-stop vehicle where warm cranking is not allowed to cause certain electronic loads (such as the head unit) to power cycle. When the start-stop vehicle goes through warm cranking, the lead acid battery voltage may dip to 6V (in the US) momentarily. The PMP7919 boost converter will, in this case, immediately respond to the transient so that its output voltage will stay in specifications, preventing down-stream electronic loads from shutting down
