SNVSA47D February 2016 – December 2022 LM5165
PRODUCTION DATA
The target full-load efficiency of this design is 88% based on a nominal input voltage of 12 V and an output voltage of 3.3 V. The required total input voltage range is 3.5 V to 65 V. The LM5165 has an internally-set soft-start time of 900 µs and an adjustable peak current limit threshold. The BOM is listed in Table 8-2.
