Description
- PMP9477.2, CISPR 25 Class 5 Rated Multi-Output Power Supply with Pre-Boost for Automotive Cluster Unit. The PMP9477 design is a conducted EMI optimized multi-output power supply for automotive cluster units. The power supply has a pre-boost stage for cold crank and start-stop operation and two buck regulators. The pre-boost stage features the LM3481 boost controller and will start to operate and regulate a 9.5V output when the input voltage drops below 9.5V. It makes the design a wide input voltage range of 4.5V to 38V suitable for 12V automotive battery systems. The design has two buck regulators following the pre-boost to generate 3 output voltages, the first stage buck generates a 5V, 2A output using the LM26003 and the second stage generates two outputs of 2.8V, 2A and 1.8V, 2A using the LM26420 (the max output power is 15W). The LM26003 is a wide Vin non-synchronous buck regulator and the LM26420 is a 5V input dual 2A, high frequency synchronous buck regulator
