XC9142E28D0R-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9142E28D0R-G is a synchronous step-up DC/DC converter manufactured by Torex Semiconductor. It operates as a boost regulator with a fixed output voltage of 2.8V and a maximum output current of 500mA. The device features a high switching frequency of 3MHz, enabling the use of small external inductors. It includes an integrated low-dropout (LDO) regulator for stable operation during startup and shutdown phases. The component supports input voltages from 0.7V to 5.5V and functions within an operating temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'E28' confirms the 2.8V fixed output setting against official datasheets. Ensure the 'D0R' package designation matches the required WLP-6 footprint for PCB layout compatibility. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.8V output is required from a variable or lower input source. The 500mA current capability suits moderate load applications. Consider the 3MHz frequency for size constraints versus the slightly higher quiescent current compared to lower-frequency alternatives. Verify input voltage range covers the minimum battery discharge level.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9142 series of synchronous step-up converters. The series is characterized by high efficiency and compact packaging options like WLP. The XC9142 family is designed for portable applications where space and battery life are critical constraints, offering integrated protection features and stable regulation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for XC9142 variants with different output voltage suffixes if 2.8V is incorrect. Verify pin-to-pin compatibility with other WLP-6 synchronous boost regulators from Torex or competitors. Ensure thermal performance meets system requirements under maximum load conditions.
