• Integrated power switches and control logic for minimal external components
• Fixed 1 MHz switching frequency enabling small passive component selection
• Built-in protection against over-temperature and short-circuit events

Applications

• Portable electronics requiring efficient power management
• Industrial control systems with stable voltage needs
• Communication equipment utilizing low-noise power supplies

Procurement Notes

Verify the specific tape-and-reel packaging configuration and quantity per reel when placing orders. Confirm that the suffix 'TSTR' corresponds to the intended shipping format. Ensure compatibility with automated assembly processes by checking reel dimensions. Cross-reference the manufacturer's latest documentation for any updates on recommended operating conditions or handling precautions prior to procurement.

Selection Notes

Consider the input voltage range and required output current when evaluating this converter. The fixed 1 MHz frequency suits applications prioritizing size reduction over extreme light-load efficiency. Evaluate thermal performance based on expected ambient temperatures and PCB copper area. Compare alternative solutions if variable frequency operation or lower quiescent current is critical for the specific design requirements.
