Procurement Notes
Verify the specific suffix E6TA against official Diodes Incorporated documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with RoHS3 standards as indicated in manufacturer records. Cross-reference the Mouser part number 522-ZXSC420E6TA for accurate sourcing details. Confirm that the SOT-23-6 package matches your PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact boost solution is required for inputs between 1.8V and 8V. The fixed 5V output simplifies design for standard logic or peripheral supplies. The SOT-23-6 package suits space-constrained applications. Verify that the 300 mA load requirement does not exceed the controller's rated capacity under all operating conditions.
Part Context
This part belongs to the ZXSC420 series of DC-DC switching controllers from Diodes Incorporated. It is categorized under PMIC voltage controllers and specifically designed for boost applications. The series targets efficient power management in small form-factor devices requiring reliable step-up conversion from single-cell batteries.
Replacement Considerations
Consult official Diodes Incorporated substitution guides for verified alternatives. Generic replacements may differ in pinout, thermal performance, or control logic. Do not assume functional equivalence without validating electrical parameters against the original datasheet.
