Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'A' indicates the fixed 5.2 V output configuration as per the official datasheet. Confirm the 'DER-G' designation corresponds to the 6-UFDFN package type. Ensure compliance with RoHS and REACH standards required for the target market. Cross-reference the manufacturer part number directly with Torex Semiconductor documentation to avoid confusion with similar series variants.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.2 V output is required from low-voltage sources starting at 0.65 V. The 500 mA output capability suits moderate load applications. Choose between 1.2 MHz and 3 MHz frequencies based on the desired trade-off between inductor size and efficiency. The synchronous design is preferred over asynchronous versions for improved performance at higher loads.
