Exact-Part Selection Insight
This regulator combines a 3.8V~30V operating/input range, 3A output-current rating and 2.2MHz switching frequency. Those three values interact with inductor/diode or FET selection, capacitor ripple requirements and thermal margin; the current rating should not be evaluated independently of input voltage and switching conditions.
Selection Notes
- Package: SOT-583
- Operating/input voltage: 3.8V~30V
- Output Voltage: 800mV~22V
- Output Current: 3A
- Frequency – Switching: 2.2MHz
Application Fit
This exact part is appropriate for designs that require a DC-DC switching regulator with the confirmed package and electrical/function parameters above. Final fit depends on the surrounding circuit, interface, thermal and mechanical requirements of the target design.
Design Considerations
Confirm the available supply rail stays inside the stated operating range, including startup and transient conditions.
Check current, power dissipation and board thermal conditions at the intended operating point rather than using the headline rating alone.
Use the exact SOT-583 footprint/package definition when checking PCB land pattern, assembly clearance and sourcing equivalence.
