XC9142E38DER-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9142E38DER-G is a synchronous step-up DC/DC converter from the Torex XC9142 series. It provides a fixed positive output voltage of 3.8 V with a maximum output current of 500 mA and a peak capability of 0.8 A. The device operates within an input voltage range of 0.65 V to 6 V. It utilizes pulse width modulation (PWM) control and supports PFM control techniques for efficiency optimization. The component is housed in a compact 6-UFDFN package with an exposed pad, measuring 1.8 x 2 mm. It functions reliably across an operating temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous rectification architecture ensures high conversion efficiency across varying load conditions.
• Integrated load disconnection function prevents reverse current flow when the device is disabled.
• Supports both PWM and PFM control modes to optimize performance based on operational requirements.

Voltage Regulators - DC DC Switching Regulators Applications

• Battery-powered systems utilizing single-cell lithium-ion or lithium-polymer sources
• Embedded circuits needing stable voltage regulation from low input sources

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DER-G against official Torex documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint, specifically the 6-UFDFN exposed pad thermal requirements. Cross-reference the fixed 3.8 V output setting with your system design needs before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.8 V output is required from inputs as low as 0.65 V. The synchronous design suits applications prioritizing efficiency over cost-sensitive non-synchronous alternatives. Consider the 6-UFDFN package constraints for thermal dissipation and board space limitations compared to larger SOT packages.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9142 series of 0.8 A step-up DC/DC converters. The series is characterized by low quiescent current and integrated load switches. The XC9142E38DER-G specifically denotes the version with a fixed 3.8 V output and the DER-G packaging configuration, distinguishing it from other voltage variants in the same family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9142 series variants with different fixed output voltages if the voltage level can be adjusted externally or if a different fixed value is acceptable. Verify pinout compatibility with packages like SOT-25-5 or other UFDFN variants before substitution.
