XC9286B09CMR-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9286B09CMR-G is a synchronous buck converter from the HiSAT-COT series by Torex Semiconductor. It operates with an input voltage range of 2.5 V to 5.5 V and provides a fixed output voltage of 900 mV at up to 1 A load current. The device features a switching frequency of 1.2 MHz and ultra-low quiescent current of 15 uA. It utilizes PWM/PFM auto control for efficiency optimization. The component is housed in a compact SOT-25-5 package and supports operation within a temperature range of -40°C to +105°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• HiSAT-COT topology enables stable operation with low-cost ceramic capacitors without requiring phase compensation.
• Integrated synchronous rectification improves conversion efficiency across wide load ranges.
• Auto PWM/PFM control mode dynamically switches between operating modes to minimize power consumption during light loads.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring efficient step-down regulation
• Battery-powered systems needing extended operational life
• Embedded circuits with strict space constraints

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CMR-G' against official datasheets to confirm package type, tape-and-reel quantity, and RoHS compliance status. Ensure the fixed 900 mV output aligns with target circuit requirements before ordering. Cross-reference manufacturer part numbers directly to avoid substitution errors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed low-voltage output near 1 V is required. The 1.2 MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the 1 A continuous current rating meets peak load demands while maintaining thermal performance within the specified operating temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9286 family of HiSAT-COT synchronous buck converters. The 'B' designation typically indicates a fixed output voltage variant, distinguishing it from adjustable versions. The CMR-G suffix specifies the SOT-25-5 surface-mount package and green (RoHS compliant) manufacturing standard.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements include other XC9286 series variants with compatible output voltages such as XC9286BxxCMR-G. Ensure substitute parts maintain the same 1.2 MHz switching frequency and SOT-25-5 footprint for board compatibility.
