Description
- PMP9458, CISPR 25, Class 5, Rated 14W Multi-Output Power Supply for Automotive Cluster Unit Reference Design. The PMP9458 reference design is a conducted EMI optimized 2-layer board power supply for automotive cluster units. The power supply has two buck regulators in cascaded connection, the first stage buck generates a 5V, 2A output using the LM26003 and the second stage generates two outputs of 2.8V, 1.5A and 1.8V, 2A using the LM26420 (the max output power in total is 14W). The LM26003 is a wide Vin non-sync buck regulator, and the LM26420 is a 5V input dual 2A, high frequency sync buck regulator. They both have automotive grade versions, qualified in AEC-Q100 Grade 1. The input voltage range of the design is 6.5V to 38V making it suitable for automotive 12V battery systems
