Selection Guidelines

Choose LM43602DSUR when you need up to 2A output, wide input voltage range, high efficiency, and small form factor

Check total load and thermal requirements to confirm suitability

Use adjustable output for flexibility across projects

Make sure your board supports surface mounting and 16-VFDFN package

Confirm RoHS and REACH compliance for regulated markets

Prefer LM43602DSUR for new designs requiring SIMPLE SWITCHER® compatibility

Usage Considerations

Pay attention to input and output voltage limits

Select appropriate external components to optimize performance (inductor, capacitors)

Ensure good thermal design and exposed pad soldering for heat management

Follow recommended layout for EMI reduction

Review switching frequency and adjust for compatible timing

Check Moisture Sensitivity Level for storage before assembly

Test regulator under maximum load, worst-case ambient temperature
