JAJSFY2B August 2018 – June 2021 LM5146-Q1
PRODUCTION DATA
With an input operating voltage as low as 3.5 V and up to 100 V as specified in Table 12-1, the LM(2)514x-Q1 family of automotive synchronous buck controllers from TI provides flexibility, scalability and optimized solution size for a range of applications. These controllers enable DC/DC solutions with high density, low EMI and increased flexibility. Available EMI mitigation features include dual-random spread spectrum (DRSS) or triangular spread spectrum (TRSS), split gate driver outputs for slew rate (SR) control, and integrated active EMI filtering (AEF). All controllers are rated for a maximum operating junction temperature of 150°C, have AEC-Q100 grade 1 qualification, and are functional safety capable.
