CASE ANALYSIS
Scenario
Designing a DC-DC buck converter for adjustable output voltage from a 12V input.
Key decisions
- Use of LM2596 for high efficiency and simple design
- Feedback resistor network to set output voltage
- Catch diode and inductor selection for continuous conduction mode
When to reuse this
Reusable for any adjustable buck converter where a fixed input voltage needs to be stepped down to an adjustable lower voltage.
