JAJSV63A August 2024 – August 2024 LM5137-Q1
ADVANCE INFORMATION
With an input operating voltage as low as 3.5V and up to 100V as specified in Table 9-1, the LM(2)514x-Q1 family of automotive synchronous buck controllers from TI provides flexibility, scalability and optimized design size for a variety of applications.
With the LM5137-Q1 and LM25137-Q1 now available to aid in functional safety system design up to ASIL D, the controller family enables DC/DC designs with high density, low EMI, and increased system reliability. All controllers are rated for a maximum operating junction temperature of 150°C and have AEC-Q100 grade 1 qualification.
