TPS92201ADRLR

Overview

The TPS92201ADRLR is a high-efficiency, synchronous buck-type LED driver IC from Texas Instruments. It supports an input voltage range of 2.5V to 5.5V and delivers a constant output current of up to 1.5A. The device integrates high-side and low-side MOSFETs for optimized performance. Operating frequencies reach 1.5MHz, with an adjustable output voltage range of 600mV to 5.5V. It features analog and PWM dimming capabilities and operates within a temperature range of -40°C to +85°C in a SOT-563 package.

Feature Summary

Integrates high-side and low-side MOSFETs for high-efficiency synchronous buck operation
Supports both analog and pulse-width modulation (PWM) dimming methods
Provides constant output current regulation for stable LED driving

Applications

Camera flash lighting systems
Test and measurement equipment illumination
Power delivery indicator circuits

Procurement Notes

Verify the specific suffix 'A' against the official datasheet to confirm pinout or functional variations compared to standard versions. Ensure the SOT-563 package type matches the target PCB footprint. Confirm RoHS compliance status if required by environmental regulations. Validate that the 1.5A current rating aligns with the load requirements. Check for moisture sensitivity level constraints during storage and handling.

Selection Notes

Select this component for applications requiring a compact, single-channel solution with inputs between 2.5V and 5.5V. It is suitable where space is limited due to the small SOT-563 package. Consider the 1.5A current limit when designing for high-power LEDs. The integrated MOSFETs simplify external component count. Verify thermal management needs for continuous 1.5A operation.

Part Context

This part belongs to the TPS92201 series of LED drivers designed for portable and battery-powered devices. It complements other variants like the TPS92201DRLR, which may differ in packaging or specific electrical characteristics. The series focuses on efficiency and size reduction for modern consumer electronics.
