CISPR 25 Class 5 Rated 6.6W Automotive Power Reference Design
PMP9398: The PMP9398 reference design is a conducted EMI optimized 6.6W power supply design for automotive application. It features the SIMPLE SWITCHER® LM46002 synchronous buck regulator and provides a 3.3V, max 2A output. The input voltage range is 4.5V to 60V suitable for 12V automotive battery supply. The reference design has the input EMI filter stage, and the conducted EMI is tested under the CISPR 25 automotive EMC standard. The design is compliant with the Class 5 conducted emissions standard.
Wide Vin Low Noise Triple Output Step Down Converter Reference Design
PMP9462: The reference design PMP9462 is a single input step-down converter with three low-noise outputs. The module uses LM43603, a synchronous step-down DC-DC converter capable of driving up to 3A of load current from an input voltage ranging 7V to 36V. The 5V output from LM43603 enables the LM26420 which further steps down this voltage to produce 1.8V and 2.5V outputs, capable of driving 1A load current each. This power supply is suitable for applications that require multiple outputs from a single input DC voltage. It provides good regulation performance over an input voltage range of 7V to 36V.
