Voltage Regulators - DC DC Switching Regulators Overview

The XC9237B2BD4R-G is a synchronous step-down DC/DC converter manufactured by Torex Semiconductor. It features a built-in high-speed switching transistor and operates within an input voltage range of 2V to 6V. The device provides a fixed output voltage of 2.15V with a maximum output current of 0.6A. It utilizes current-mode control for stable operation and supports a switching frequency of 3.45MHz. The component is housed in a compact PBGA5 package (3x3mm) with a 0.254mm terminal pitch, suitable for space-constrained applications.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a synchronous rectification structure with a built-in driver transistor to minimize external component count.
• Employs current-mode control architecture to ensure rapid transient response and stable regulation under varying load conditions.
• Features a low quiescent current design to enhance energy efficiency during standby or light-load operations.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring efficient power management from single-cell lithium-ion batteries
• Embedded systems utilizing microcontrollers or digital signal processors with low voltage requirements
• Battery-operated consumer electronics needing compact power supply solutions

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status as per manufacturer standards. Confirm the PBGA5 package dimensions and thermal pad requirements against your PCB layout specifications. Ensure the fixed 2.15V output aligns with your system's voltage rail needs, as this variant does not support adjustable outputs. Cross-reference the datasheet revision date to confirm compatibility with your manufacturing processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 2.15V output is required rather than an adjustable voltage option available in other XC9237 variants. The 0.6A output current capability suits moderate load applications, while the 3.45MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. The PBGA5 package offers a footprint advantage over larger SOIC packages but requires appropriate soldering techniques for fine-pitch BGA assembly.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the XC9237 series of synchronous step-down converters, which are designed for high efficiency and compactness. The series includes various output voltage options and packaging types to accommodate different design constraints. The XC9237B2BD4R-G specifically targets applications needing a precise 2.15V output in a small form factor, leveraging the series' robust current-mode control and integrated power switches.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements within the same series include XC9237B2CD4R-G (2.5V output) or XC9237B2DD4R-G (2.8V output) if voltage tolerance allows. For pin-compatible alternatives with different voltages, verify the output setting suffix. Other packages like PDSO6 may offer similar electrical characteristics but require layout adjustments due to differing pinouts and thermal properties.
