Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix D4R-G against official datasheets to confirm the 1.65V fixed output and package type. Ensure compatibility with the required switching frequency configuration. Confirm RoHS compliance status if mandated by project specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 1.65V output is required within a 6V input limit. Choose the G-type variant for the 1.8V minimum input specification. Consider the manual mode switch feature if design flexibility between noise reduction and light-load efficiency is needed. Verify that the 600mA load requirement fits within the thermal constraints of the SC-74A package.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9237 series, which includes variants with adjustable outputs (D/F types) and other fixed voltages (A/B/C/E/G types). The series shares common architectural features such as built-in oscillators and protection circuits. The XC9237 series is designed to replace older linear regulators in applications demanding higher efficiency and lower heat dissipation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9237B3DCMR-G offers a similar 600mA capacity but differs in output voltage and package. XC9236A08D4R-G provides automatic PWM/PFM switching instead of manual selection. XC9235G3KDMR utilizes constant PWM control without PFM support. Verify pinout and electrical parameters before substituting any alternative part numbers.
