XC9220B095ER-G

DC DC Switching Controllers Overview

The XC9220B095ER-G is a synchronous buck DC-DC switching controller manufactured by Torex Semiconductor. It operates with an input voltage range of 2.8 V to 16 V and delivers a maximum output current of 3 A. The device features a fixed internal switching frequency of 575 kHz, enabling the use of compact external components. It provides an adjustable output voltage capability and supports up to 100% duty cycle operation for low dropout performance. The controller is housed in a compact USP-6 package (1.8x2 mm) and is designed for efficient power management in space-constrained applications.

DC DC Switching Controllers Feature Summary

• Integrates high-side and low-side drivers for synchronous rectification to improve conversion efficiency.
• Supports adjustable output voltages with a maximum duty cycle of 100% for minimal voltage drop.
• Utilizes a fixed 575 kHz switching frequency to minimize passive component size requirements.
• Includes built-in protection mechanisms such as overcurrent protection and thermal shutdown.

DC DC Switching Controllers Applications

• Portable electronic devices requiring efficient step-down power regulation
• Battery-powered systems needing extended operational life
• Embedded systems with strict space limitations for power components

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'ER' confirms the USP-6 package and tape-and-reel orientation. Ensure the 'G' suffix indicates compliance with RoHS and halogen-free standards as per manufacturer specifications. Confirm that the intended application voltage range falls within the 2.8 V to 16 V input limits. Validate that the required output current does not exceed the 3 A rating under specified thermal conditions.

DC DC Switching Controllers Selection Notes

Select this component when a compact synchronous buck solution is required with a fixed switching frequency near 575 kHz. It is suitable for designs prioritizing small footprint due to the USP-6 package. Consider this part if the input supply varies between 2.8 V and 16 V. Ensure the load current requirements align with the 3 A maximum output capability. Evaluate thermal management needs given the small package size.
