- Fixed 500kHz switching frequency
- Wide input voltage capability up to 18.5V
Applications
- Portable electronic devices
- Battery-powered systems
- Embedded power supplies
Procurement Notes
Verify the specific suffix 'H' against the manufacturer's official datasheet to confirm the exact output voltage setting or feature set, as suffixes often denote critical electrical variations. Ensure the SOT-23-5 package type matches your PCB footprint requirements. Confirm RoHS compliance status through the latest environmental documentation provided by Nisshinbo Micro Devices before finalizing procurement.
Selection Notes
Select this component when a fixed 500kHz frequency is required for EMI management in space-constrained designs. The wide input range accommodates various battery chemistries. Compare against other R1224N variants if different switching frequencies or shutdown features are needed. Ensure external components support the 500kHz operation for optimal efficiency.
Part Context
This part belongs to the R1224N series of step-down DC/DC controllers. The series offers various output voltage options distinguished by alphanumeric suffixes. All members share the core buck topology and SOT-23-5 packaging, providing a standardized platform for low-power voltage regulation across different application voltage requirements.
Replacement Considerations
R1224N362G-TR-FE and R1224N602H-TR-FE are documented members of the same family. Verify if alternative suffixes meet the specific voltage or feature requirements. Cross-reference pinouts and thermal characteristics to ensure compatibility during substitution.
