5.1.2 Development Support

With an input operating voltage as low as 3.5V and up to 100V as specified in Table 5-1, the family of synchronous buck controllers from TI provides flexibility, scalability, and optimized design size for a variety of applications.

With the LM5137F and LM25137F available to aid in functional safety system design up to SIL 3, the controller family enables DC/DC designs with high density, low EMI, and increased system reliability.
