BOM rule hits · not reviewed — A hit means a BOM line matched this category's rules (ruleset 1.0.1+12960cbec977). It is a lead to read, not a located or reviewed circuit; several lines in one category are not several circuits.
Selection parameter template (suggestion)
What one usually states when choosing a circuit of this kind — not the parameters of any design or module listed here, and never a filter.
| Parameter | Suggested range or common values | Where it comes from |
|---|---|---|
| Input voltage range (V)Decisive | 2.5 to 60 V | Inherited from Switching DC-DC conversion |
| Output voltage (V)Decisive | 0.6 to 48 V | Inherited from Switching DC-DC conversion |
| Output current (A)Decisive | 0.1 to 10 A | Inherited from Switching DC-DC conversion |
| Switching frequency (kHz)Important | 200 to 3,000 kHz | Inherited from Switching DC-DC conversion |
| Efficiency (%)Important | 80 to 97 % | Inherited from Switching DC-DC conversion |
| Quiescent current (uA)Important | 1 to 1,000 uA | Inherited from Switching DC-DC conversion |
| Synchronous rectificationFor reference | Yes / no | Inherited from Switching DC-DC conversion |
| Output ripple (mV)For reference | 5 to 50 mV | Inherited from Switching DC-DC conversion |
