LM2426TA

Overview

The LM2426TA is a monolithic triple CRT driver manufactured by National Semiconductor. It features a switching frequency of 280 kHz and operates within an input voltage range of 15 V to 40 V, with a nominal input of 24 V. The device utilizes pulse width modulation control mode and is housed in a DSO14 or LLP-14 package measuring 6 mm in length.

Feature Summary

• Monolithic integration of three independent driver channels
• High-speed switching capability with 7.5 ns response time
• Pulse width modulation control for stable regulation

Applications

• CRT display driver circuits
• Video signal processing systems
• Monitor deflection drivers

Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, as both entities are associated with this part number in public records. Confirm the specific package variant (DSO14 or LLP-14) matches the design requirements. Ensure the component meets the necessary regulatory compliance standards for the intended application environment.

Selection Notes

Select this component for applications requiring integrated triple-channel driving capabilities. Consider the 280 kHz switching frequency and 7.5 ns speed when designing timing-critical video circuits. Verify that the 15 V to 40 V input range aligns with the system power supply specifications.

Part Context

This component belongs to the family of switching regulators and controllers. It shares the 280 kHz switching frequency characteristic found in other parts like the LM2676SD-12. The device serves as a specialized driver solution distinct from general-purpose linear regulators or synchronous buck controllers.
