XC9142B50C0R-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9142B50C0R-G is a synchronous step-up DC/DC converter from the Torex Semiconductor XC9142 series. It operates with an input voltage range of 650 mV to 6 V and provides a fixed output voltage of 5 V. The device supports a maximum output current of 500 mA and features a low quiescent current of 26 uA. It utilizes a 3 MHz switching frequency and is housed in a compact SOT-25-5 package suitable for surface mount applications.

• Low-voltage input power management systems
• Embedded electronics with strict space constraints

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix C0R against official Torex documentation to confirm pinout and functional compatibility, as suffixes often denote specific package or tape-and-reel variations. Ensure the source document explicitly lists XC9142B50C0R-G to avoid confusion with similar models like B50DMR-G which may have different electrical characteristics.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from inputs as low as 650 mV. The 3 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 500 mA load requirement aligns with the thermal capabilities of the SOT-25-5 package in the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9142 family of synchronous step-up converters. The 'B' typically indicates a specific version within the series, while '50' denotes the 5 V output setting. The 'C0R' suffix specifies the package type and reel configuration. This series is designed for high-efficiency power management in portable applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

XC9142B50DMR-G shares the same core electrical specifications including 5 V output and 500 mA current but differs in switching frequency (3 MHz vs 3 MHz) and potentially internal control logic. Verify pin-to-pin compatibility and thermal performance before substitution.
