Exercise (PageIndex{8}) It was mentioned in Section 5.2.4 that alternative compensation possibilities for the gain-of-ten amplifier include lowering the magnitude of the loop transmission at all frequencies by a factor of 6.2 and lowering the location of the lowest-frequency pole in the loop transfer function by a factor of 6.2 by selecting appropriate lag-network parameters.
This article describes how, when using the 2-channel DC/DC converter LT8650S, when channel 1 (CH1) is used with an internal compensation circuit and channel 2 (CH2) is used with an external compensation circuit, mutual interference (large change in phase margin characteristics) occurs. We will introduce the results of verifying that this does not occur.
