XC9291B14D1R-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9291B14D1R-G is a non-isolated step-down DC/DC converter manufactured by Torex Semiconductor. It features an input voltage range of 2.5 V to 6 V and provides a fixed output voltage of 1.4 V at a maximum output current of 600 mA. The device utilizes HiSAT-COT control for stable operation with small external components. It operates within a temperature range of -40°C to +105°C and is housed in a compact LGA-6B01 package measuring 1.2 mm x 1.2 mm x 0.3 mm.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Employs HiSAT-COT control technology for high-speed transient response and minimal external component requirements.
• Supports both PWM and PFM modes for optimized efficiency across varying load conditions.
• Integrated synchronous rectification reduces power loss and improves overall conversion efficiency.

Voltage Regulators - DC DC Switching Regulators Applications

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix D1R against official datasheets to confirm the fixed 1.4 V output voltage, as suffix variations indicate different electrical characteristics. Ensure compatibility with the LGA-6B01 footprint during PCB layout. Confirm RoHS compliance status through manufacturer documentation before integration into regulated products.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.4 V output is required from a 2.5 V to 6 V input source. The LGA-6B01 package is suitable for applications with severe space limitations. Consider the 600 mA current limit and operating temperature range to ensure it meets the system's thermal and power demands without exceeding specifications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9291 series of extremely small step-down DC/DC converters. The series is characterized by its low profile and high integration, designed for modern electronics where board space is at a premium. The B14 variant specifically denotes the fixed output voltage configuration within this family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Cross-reference with other XC9291 variants such as XC9291B18D1R-G or XC9291B15D1R-G if different fixed output voltages are needed while maintaining the same package and performance profile. Verify pinout compatibility before substitution.
