Hi buck 芯片都可以做这种topy转换实现负压输出，包括LM16006.
Is TPS62561 a right solution? (It's acceptable, if we need to design an extra inductor/bead to improve ripple performance) Application: 3.3Vin to -0.8Vout @ 200mA load current. Regards, Ben Hi Ben, A buck converter in an inverting buck-boost topology can be ...
A buck converter can be used to generate a negative output voltage from a positive input voltage if the circuit is configured as an inverting buck-boost converter. The circuit design is straightforward, but these important points should be remembered. The output current is less than the average ...
Figure 1.Generic topology of an inverting buck-boost converter. Now it’s time for me to create an implementation in LTspice. Want to review the fundamentals before diving in? Read “What is a Switching Voltage Regulator?” for a review of general concepts relating to DC-DC converters. ...
This application note describes how to implement the ADP2384/ ADP2386 in a synchronous inverting buck-boost topology to generate negative output voltages from positive input power supplies.
www.ti.com Technical Article Vary the Output Voltage in an Inverting Buck-boost Topology Nikhil Jotwani In this blog post, I'd like to discuss a methodology for providing a variable output voltage in an inverting buck-boost topology. In this topology, the choice of resistors on the feedback...
In such instances it is possible to configure the buck converter into an inverting buck-boost topology, where the output voltage is negative with respect to ground. Basic buck topology To understand the inverting buck-boost circuit operation, first consider the basic topology of the buck converter...
