TL2845D-8

Overview

The TL2845D-8 is a current-mode PWM controller manufactured by Texas Instruments, designed for DC/DC switching applications. It operates within an input voltage range of 12 V to 30 V, with a nominal rating of 15 V. The device supports a maximum switching frequency of 500 kHz and provides a maximum duty cycle of 50%. It features a SOIC-8 surface-mount package and functions as a single-output regulator. The component is RoHS compliant and classified under EAR99.

Feature Summary

• Implements current-mode pulse width modulation control architecture
• Supports boost, flyback, and forward converter topologies
• Provides integrated transistor driver output stage

Applications

• Boost converter designs
• Flyback power supply implementations
• Forward converter circuits

Procurement Notes

Verify the specific suffix 'D-8' against the manufacturer's official documentation to confirm the exact package variant and tape/reel specifications. Ensure compliance with RoHS standards and check for any recent product change notices or lifecycle status updates prior to finalizing procurement orders.

Selection Notes

Select this component for applications requiring a 500 kHz switching frequency and a 50% maximum duty cycle limit. It is suitable for designs operating between 12 V and 30 V input voltages. Consider the SOIC-8 package constraints and the -40°C to 85°C operating temperature range when evaluating thermal management requirements.

Part Context

This part belongs to the TL284x series of switching controllers from Texas Instruments. It shares functional similarities with other members like the TL2845DR-8 but differs in packaging and distribution format. The series is widely used in general-purpose power management solutions requiring reliable current-mode control.

Replacement Considerations

TL2845DR-8 is listed as a manufacturer-recommended alternative.
