Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix UC64X against official datasheets to confirm exact output voltage settings and pinout compatibility. Confirm RoHS compliance status and check for obsolescence notices, as availability may vary by region. Ensure ESD handling protocols are followed during assembly due to the WLCSP package type.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a small form factor and digital voltage adjustment are required. Compare against the FAN53526UC128X and FAN53526UC168X variants if different default voltage configurations or packaging options are needed. Ensure the 3 A current rating meets load requirements and that the 2.4 MHz frequency aligns with EMI constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the TinyBuck series, designed for low-power applications requiring high density. The FAN53526 family integrates power switches and control logic into a single chip, reducing external component count compared to discrete solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct substitutes within the FAN53526 series such as FAN53526UC128X or FAN53526UC168X, ensuring pin compatibility and voltage range alignment.
