Overview
The TPS92201ADRVR is a high-efficiency synchronous buck LED driver IC from Texas Instruments. It operates with an input voltage range of 2.5V to 5.5V and delivers a constant output current of up to 1.5A. The device features a fixed switching frequency of 1.5MHz and supports analog and PWM dimming. It includes internal soft-start functionality and offers adjustable output voltage from 600mV to 5.5V. Designed for compact applications, it is available in a 6-WSON package.
Feature Summary
- Integrates high-side and low-side MOSFETs for high efficiency
- Supports both analog and PWM dimming methods
- Includes internal soft-start circuitry
- Operates in power-save mode for improved light-load efficiency
Applications
- Battery-powered LED lighting systems
- Portable electronic device illumination
- Low-voltage LED backlighting
- General-purpose LED driving in space-constrained designs
Procurement Notes
Verify the specific suffix 'ADRVR' corresponds to the WSON-6 package and reel/cut-tape availability. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure design-in compatibility with required thermal dissipation capabilities for the selected operating conditions.
Selection Notes
Select this component when a single-channel, high-efficiency solution is needed for low-voltage LED loads. Consider the 1.5A current limit and 5.5V maximum input voltage constraints. Evaluate the 6-WSON footprint against board space limitations. Verify that the required dimming interface matches the supported analog or PWM inputs.
Part Context
This part belongs to the TPS92201A series of LED drivers. It is designed as a cost-effective, small-footprint alternative to discrete solutions. The synchronous buck topology reduces external component count compared to non-synchronous designs. It targets applications requiring high efficiency within strict size and voltage constraints.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family, such as TPS92201ADRLR, noting package differences. Verify if newer generations offer improved efficiency or additional features while maintaining electrical compatibility.
