Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix CMR-G against official Torex documentation to confirm package type and tape/reel specifications. Ensure compatibility with required input voltage ranges and thermal constraints for the target application environment before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.9 V output is required from a 2 V to 6 V input source. It is suitable for applications prioritizing space savings due to its small SOT-25-5 footprint and low external component count. Consider the 600 mA current limit and 1.2 MHz frequency when designing the passive filter network.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9236 series of 600mA synchronous step-down converters. Unlike the XC9235 (PWM only) or XC9237 (switchable mode), the XC9236 series specifically offers automatic PWM/PFM switching control. This series is designed to provide high efficiency and stable power supply configurations using minimal external components.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9236A29CMR-G is a fixed-output variant. Direct replacements must match the 2.9 V output, 600 mA rating, and SOT-25-5 package. Other XC9236 series parts with different output voltages are not electrically compatible substitutes.
