XC9221A095ER-G

DC DC Switching Controllers Overview

The XC9221A095ER-G is a step-down DC-DC switching controller manufactured by Torex Semiconductor Ltd. It operates with an input voltage range of 2.8V to 16V and features a fixed switching frequency of 500kHz. The device supports a maximum duty cycle of 100% and provides a single positive output configuration via a transistor driver interface. It lacks synchronous rectification and clock synchronization capabilities. The component is rated for an operating temperature range of -40°C to +85°C and is housed in a 6-USPC (1.8x2) surface-mount package.

DC DC Switching Controllers Feature Summary

• Includes enable pin control for power management

DC DC Switching Controllers Applications

• Battery-powered portable electronic devices
• General purpose step-down power supply circuits
• Embedded systems requiring regulated lower voltage rails

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'ER-G' against the official Torex Semiconductor datasheet to confirm the exact package type and tape-and-reel specifications. Ensure that the required switching frequency and input voltage range align with the target circuit design before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when a non-synchronous buck controller is required for cost-sensitive applications. The 500kHz frequency offers a balance between efficiency and external component size. Verify that the load current requirements are met by the external MOSFET selection, as the IC only provides the gate drive signal.
