XC9236G08D4R-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9236G08D4R-G is a synchronous step-down DC/DC converter manufactured by Torex Semiconductor. It features a fixed output voltage of 0.8 V and supports an output current of 600 mA. The device operates with an input voltage range of 1.8 V to 6 V. Key electrical parameters include a switching frequency of 3 MHz and a typical quiescent current of 21 uA. It utilizes a 6-XDFN package with an exposed pad for thermal management.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates high-side and low-side N-channel MOSFETs for efficient synchronous rectification
• Maintains constant switching frequency under PWM control for simplified noise countermeasures
• Supports PFM/PWM mode selection to optimize efficiency at light loads

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring stable low-voltage power rails
• Battery-powered systems needing extended operational life through low standby current
• Embedded circuits utilizing single-cell lithium-ion or lithium-polymer batteries

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix D4R against the manufacturer's official datasheet to confirm the package type and tape-and-reel specifications. Ensure compatibility with the required 0.8 V fixed output voltage, as other variants in the XC9236 series offer adjustable or different fixed outputs. Confirm that the 600 mA load requirement does not exceed the thermal limits of the selected PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 0.8 V output is strictly required rather than an adjustable configuration. The 3 MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Verify that the system ground plane can support the thermal dissipation requirements of the exposed pad design for reliable operation within the specified temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9236 series of synchronous buck converters from Torex Semiconductor. The series is characterized by high integration and low power consumption, designed for space-constrained applications. The G08 variant specifically provides a fixed 0.8 V output, distinguishing it from adjustable models like the XC9236A series or other fixed voltage options within the same family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes may include other XC9236 series parts with compatible packages if the fixed voltage constraint is relaxed. Cross-reference with XC9236Gxxxx-R-G variants for identical packaging but different output voltages. Ensure any replacement maintains the 600 mA current rating and similar thermal characteristics.
