PMP8903
概述
In today’s start-stop systems, it is common for battery voltages to dip well below the nominal 12V rating. PMP8903 represents a very common start-stop application where that battery voltage can drop as low as 5V, and a 5V output is still needed for CAN and also as an intermediate bus. This design also features two tiny synchronous low-voltage buck regulators generating 3.3V and 1.1V from the 5V intermediate rail, contributing to an overall solution size that is very compact for space-constrained automotive environments. For an additional output voltage version of the design, see PMP8903.2
