L6564DTR

Overview

The L6564DTR is a transition mode power factor correction controller manufactured by STMicroelectronics. It operates within a supply voltage range of 10.3V to 22.5V and features a startup current of 90 µA. The device is housed in a 10-SSOP package with a width of 3.90mm. It supports an operating temperature range from -25°C to 125°C. The component is designed for discontinuous conduction mode applications.

Feature Summary

• Transition mode operation for high efficiency
• Low startup current consumption
• Surface mount packaging

Applications

• Power factor correction circuits
• AC-DC power supplies
• SMPS preregulators

Procurement Notes

Verify the specific suffix 'DTR' indicates tape and reel packaging against official datasheets. Confirm the active status and lead times directly with STMicroelectronics or authorized distributors, as availability may vary by region.

Selection Notes

Select this component for applications requiring transition mode PFC control. Ensure the design accommodates the 10.3V to 22.5V supply range and the thermal requirements of the 10-SSOP package within the specified temperature limits.

Part Context

The L6564DTR belongs to the L6564 family of PFC controllers. It shares core functionality with the L6564D but differs in packaging format. This series is optimized for compliance with energy saving regulations and mains current distortion standards.

Replacement Considerations

L6564D is the direct equivalent in tube packaging. L6561 offers similar transition mode features with different pinout and package options.
