+/-40-V inverting buck-boost with auxiliary output reference design
Description
This reference design uses the TPS54560B in an inverting buck-boost topology to generate a -40-V output from a +5-V input. An auxiliary winding generates a +40-V output with reference to the same ground. For applications needing a positive and negative voltage: the buck topology provides a low-noise output with a minimal component count.
Features
- Less than 0.5% voltage ripple on each output for noise sensitive loadsZener clamp keeps output voltages balanced during extreme cross loading Low component count requires only 26 power componentsCompact size (40mm x 55mm) minimizes solution size area
Applications
- Spectrum analyzer
