This document introduces a high-performance, low-EMI DC/DC converter that is available in a small LGA package and can provide up to 2A of current to a system.
The document details a specific application note excerpt regarding diode turn-on time issues in switching regulators. It explains how fast transition times can cause overvoltage stress on ICs due to diode parasitics, necessitating careful component selection and testing.
A separate section focuses specifically on the LTM8032 switching step-down regulator. It describes an emissions test performed in a 5-meter chamber at maximum power output (10V at 2A) and input voltage (36V). The results show that the device easily meets CISPR 22 Class B limits with a significant margin of approximately 20dB.

Yes, it easily meets the CISPR 22 class B limits with a margin of about 20dB.
The test was performed using a maximum input voltage of 36V.
