Common topologies include buck, boost, buck‑boost, flyback, forward, half‑bridge, and full‑bridge converters.

Typical components include a controller IC (with or without integrated switches), inductors or transformers, rectifiers, and capacitors. For regulated outputs, some form of feedback circuitry is also required to maintain a stable voltage.

A discrete power supply uses individual components such as controllers, switching transistors, transformers, inductors, and capacitors to build a converter. This approach offers maximum flexibility, allowing engineers to hand-pick each part to optimize for specific performance goals like thermal management, high power density, or low cost.

Typical protection functions include overcurrent protection, overvoltage or undervoltage protection, thermal shutdown, and short‑circuit protection.

Discrete designs are preferred when high flexibility, custom layout, performance optimization, or cost advantages at high volumes are required.
