JAJSKQ3D February 2016 – December 2022 LM5165
PRODUCTION DATA
The target full-load efficiency is 91% based on a nominal input voltage of 12 V and an output voltage of 5 V. The required input voltage range is 5 V to 65 V. The LM5165X is chosen to deliver a fixed 5-V output voltage. The switching frequency is set by resistor RRT at 220 kHz. The output voltage soft-start time is 6 ms. The required components are listed in Table 8-1.
