TPS61500PWPR

Overview

The TPS61500PWPR is a high-brightness LED driver IC from Texas Instruments, featuring a boost topology with an internal 3A power switch. It operates on an input voltage range of 2.9V to 18V and supports output voltages up to 38V. The device integrates analog and PWM dimming capabilities and functions at switching frequencies between 200kHz and 2.2MHz. Packaged in a 14-HTSSOP surface-mount format, it is designed for applications requiring efficient DC-DC regulation for LED backlighting systems.

Feature Summary

• Integrates a 3A internal power switch capable of driving multiple high-power LEDs
• Supports both analog and pulse-width modulation (PWM) dimming methods
• Features wide input voltage compatibility for flexible system design

Applications

• LED backlighting systems
• High brightness LED driver circuits
• Portable electronic display illumination

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 14-HTSSOP footprint matches the target PCB layout dimensions. Ensure compliance with RoHS3 standards if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when a single-channel boost converter with integrated switching capability is required for LED illumination. Consider the 3A current limit and 18V maximum input constraint against load requirements. Evaluate thermal performance within the -40°C to +85°C operating range for the intended enclosure environment.
