LINEAR How to Produce Negative Output Voltages from Positive Inputs Using a Module Step-Down Regulator Design Note 1021 Jaino Parasseril

Update: 29 September, 2023

This article describes how to generate negative output voltages from positive inputs using Linear Technology's DC/DC step-down μModule® regulators. A conventional buck μModule regulator can be easily configured as an inverting buck-boost converter to generate negative output voltages. The article uses LTM®8025 as an example to demonstrate how to achieve negative output voltages with level-shifting circuitry for synchronization. This approach can also be applied to other μModule regulators such as LTM8022, LTM8023, and LTM8027.
