How to Produce Negative Output Voltages from Positive Inputs
Using a ВµModule Step-Down Regulator
Design Note 1021
Jaino Parasseril
Introduction
Linear TechnologyвЂ™s DC/DC step-down ОјModule В®
regulators are complete switchmode power supplies in a
surface-mount package. They include the DC/DC controller, inductor, power switches and supporting circuitry.
These highly integrated regulators also provide an easy
solution for applications that require negative output
voltages. In other words, these products can operate as
inverting buck-boost regulators. As a result, the lowest
potential in the circuit is not the standard 0V, but вЂ“VOUT,
which must be tied to the ОјModule regulatorвЂ™s GND. All
signals are now referred to вЂ“VOUT.
For this discussion, the LTMВ®8025 (36V, 3A) is used to
demonstrate how a buck ОјModule regulator can be altered
to produce a negative output voltage with level-shifting
circuitry for synchronization. This approach can be applied to other ОјModule regulators, such as the LTM8022
(36V, 1A), LTM8023 (36V, 2A) and LTM8027 (60V, 4A).
Design Guide
A conventional buck (step-down) ОјModule regulator
can be easily conп¬Ѓgured to generate negative output …
