In order to generate a negative output voltage from a positive input voltage, the designer would usually opt for the buck-boost topology or possibly a SEPIC converter, both of which offer reasonable efficiency that is much higher than a linear regulator. However, the same outcome can be reached with a buck converter.
This application note looks at the SiP12116 configured as a negative output buck converter. The buck topology is conventionally used to convert a larger bus or system voltage into a smaller voltage. The advantage of using a buck converter is that efficiency is very high when compared to a linear regulator performing the same conversion.
The COT converters can also be configured in a buck-boost topology, allowing for a negative output voltage. This application note looks at the SiP12116 configured as a negative output buck converter. The buck topology is conventionally used to convert a larger bus or system voltage into a smaller voltage.
With a slight alteration to the nodal references of a synchronous buck converter, we can create a negative boost converter, as shown in Fig. 1. This will suit applications that need to generate complimentary output voltages, such as audio, or industrial applications requiring negative voltage levels, such as IGBT gate drive turn-off.
This circuit offers the advantages of the positive output buck converter in the sparsely supported negative output switching regulator application. The circuitry is built around the SiP12116 synchronous buck converter, which has a fixed frequency of 600 kHz and offers a simple design with outstanding efficiency.
The ideal duty cycle for the inverting power supply is shown in Equation 4, neglecting the losses of the power switching, inductor and diode drop. The output voltage, VO, is negative and the input voltage, VI, is positive yielding a positive result for Equation 4. in Equation 4. Assuming 18 V for V of –12 V, the maximum duty cycle, Dmax, is 0.40.
