With an input operating voltage as low as 3 V and up to 36 V as specified in Table 7-1, the LM6k family of automotive synchronous buck converters from TI provides flexibility, scalability and optimized solution size for a range of applications. These converters enable DC/DC solutions with high density, low EMI and increased flexibility. Available EMI mitigation features include pseudo-random spread spectrum (PRSS), integrated input bypass capacitors, RBOOT-configured switch-node slew rate control, and optimized package design with symmetrical VIN and PGND pins that shield a small switch-node copper area. All converters are rated for a maximum operating junction temperature of 150°C, have AEC-Q100 grade 1 qualification, and are functional safety capable.
