XC9287B13CPR-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9287B13CPR-G is a synchronous buck converter from the XC9287 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 1.3 V at up to 1.5 A output current. The device utilizes HiSAT-COT control for stable operation without requiring an external compensation capacitor. It features a switching frequency of 1.2 MHz and a typical quiescent current of 15 uA. The component is housed in a SOT-89-5 package and supports a junction temperature range from -40°C to +105°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• HiSAT-COT control architecture ensures stability without external compensation capacitors

• Embedded circuits needing low quiescent current operation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix CPR against official datasheets to confirm the SOT-89-5 package and 1.2 MHz frequency variant. Ensure compatibility with your PCB footprint and thermal requirements. Cross-reference the manufacturer part number directly with Torex Semiconductor documentation to avoid confusion with other XC9287 variants that may share similar electrical characteristics but differ in packaging or switching speed.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.3 V output is required within a 2.5 V to 5.5 V input window. The SOT-89-5 package suits applications with moderate space constraints compared to smaller footprints. Consider the 1.2 MHz switching frequency for balancing EMI and passive component size. Verify that the 1.5 A load capability meets the system's peak current demands under all operating conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9287 family of HiSAT-COT synchronous buck converters. The family is characterized by high efficiency and simplified design due to the elimination of external compensation components. The XC9287B13CPR-G specifically denotes the 1.3 V output version in the SOT-89-5 package, distinguishing it from other output voltages and package options like the USP-C-EP-6.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for XC9287B13DER-G if a USP-C-EP-6 package is acceptable, noting its higher 3 MHz switching frequency. Verify pinout compatibility before substitution. Other XC9287 variants with different output voltages are not direct replacements unless the circuit allows for voltage adjustment.
