TPS92001D

Overview

The TPS92001D is a general-purpose LED lighting PWM controller from Texas Instruments, designed for single-stage AC-DC offline switcher applications. It supports flyback and buck topologies with a maximum supply voltage of 21V and provides a 5V output. The device operates at a switching frequency of 100kHz and features Triac dimming capability. Packaged in an 8-VSSOP format, it functions within a junction temperature range of -40°C to 105°C.

Feature Summary

• Integrated control and drive circuitry optimized for single-stage LED lighting designs
• Supports Triac dimming functionality for compatible lighting systems
• Capable of flyback and buck converter topologies for efficient power conversion

Applications

• General purpose LED lighting systems
• AC-DC offline switcher implementations
• Triac dimmable LED drivers

Procurement Notes

Verify the specific suffix (e.g., D vs DGK) against the manufacturer datasheet to confirm package type and availability status. Some variants may be marked as obsolete or have limited stock. Ensure the ordering part number matches the required pinout and thermal specifications for your PCB layout. Cross-reference with official Texas Instruments documentation to avoid counterfeit components.

Selection Notes

Select this component for applications requiring integrated PWM control in single-stage AC-DC converters. It is suitable for designs needing Triac dimming support and operating within a 21V input limit. Consider the 8-VSSOP package constraints and 100kHz switching frequency when designing magnetic components and thermal management solutions for the target LED load.

Part Context

The TPS92001D belongs to the TPS92001/2 family of general LED lighting PWM controllers. These devices integrate essential control and drive circuitry to simplify single-stage design architectures. They are engineered specifically for AC-DC offline switcher applications, offering a compact solution for driving LED arrays with high efficiency and minimal external component count.

Replacement Considerations

Check for the TPS92001DGK variant which shares similar electrical characteristics but utilizes an 8-TSSOP/MSOP package. Verify pin compatibility and thermal performance before substitution. Consult the official datasheet for any functional differences between package options.
