A versatile PoL (Point of Load) power supply ASIC for industrial encoder applications. It powers a micro-controller, a sensor ASIC, communication chip, … close to its application. The ASIC generates 4 power supply levels with a single inductor and contains a digital controller for maximal versatility:
- Single stage, fully integrated and non-isolated: saves energy, size and cost by eliminating the need for an intermediate bus, transformers and reducing BOM (Bill-Of-Material)
- Combines a digital versatile controller with diagnostics and integrated low-ohmic power switches in a single package to deliver required currents with reduced component count and improved performance under dynamic load conditions
- Minimizes losses caused by voltage drops, helps overcome noise sensitivity and EMI emission issues
