L6569AD

Overview

The L6569AD is a high-voltage half-bridge gate driver manufactured by STMicroelectronics. It operates within a supply voltage range of 10 V to 16.6 V and supports a minimum operating temperature of -40 °C and a maximum of +125 °C. The device features two drivers with two outputs, utilizing a PDIP-8 through-hole package. It draws a working supply current of 25 mA and is part of the L6569 series.

Feature Summary

• High-voltage half-bridge architecture for driving power switches
• Integrated oscillator for frequency generation
• Synchronous high-side and low-side correlation

Applications

• Offline flyback converters
• Resonant converter topologies
• Power factor correction circuits

Procurement Notes

Verify the active status and lead times directly with STMicroelectronics or authorized distributors, as availability may vary. Confirm that the PDIP-8 through-hole package meets your PCB assembly requirements. Ensure compliance with RoHS standards and check for any specific environmental certifications required for your manufacturing process before finalizing orders.

Selection Notes

Select this component when a robust half-bridge driver with integrated oscillation is required for offline power supplies. The PDIP-8 package suits through-hole applications where space constraints are less critical than in surface-mount designs. Consider the 10 V to 16.6 V supply range and wide temperature operation for industrial or consumer environments.

Part Context

The L6569AD belongs to the L6569 family of high-voltage half-bridge drivers from STMicroelectronics. This series is designed for use in various switching power supply applications, offering a complete solution with built-in timing functions. The AD suffix typically denotes a specific variant within the broader L6569 product line, often sharing core electrical characteristics with other members like the L6569D.

Replacement Considerations

The L6569A is a documented alternative within the same family, though it utilizes a DIP-8 through-hole package similar to the L6569AD. Verify pin compatibility and thermal performance when substituting.
