SNVSA47D February 2016 – December 2022 LM5165
PRODUCTION DATA
The input capacitor, CIN, filters the high-side MOSFET triangular current waveform, see Figure 8-36. To prevent large ripple voltage, use a low-ESR ceramic input capacitor sized for the worst-case RMS ripple current given by IRMS = IOUT/2. In this design example, choose a 1-µF, 100-V ceramic input capacitor with X7S dielectric and 0805 footprint.
