TPS61500PWP

Overview

The TPS61500PWP is a high-brightness LED driver IC from Texas Instruments, housed in a 14-pin TSSOP package. It integrates a 3-A, 40-V internal power switch and supports an input voltage range of 2.9 V to 18 V. The device utilizes current mode PWM regulation with a feedback voltage set to 200 mV via an external sensor resistor. It features a maximum duty cycle of 93% and operates within a temperature range of -40°C to +85°C. Designed for efficient energy conversion, it can drive four 3-W LEDs from a 5-V input or eight 3-W LEDs from a 12-V input.

Feature Summary

• Integrates a robust 3-A, 40-V internal power switch for high-power applications
• Supports wide input voltage range from 2.9 V to 18 V for flexible power sources
• Enables multiple dimming methods for versatile lighting control
• Utilizes current mode PWM regulation for precise LED current control

Applications

• LED signage and displays
• Ambient and office lighting systems
• General illumination fixtures
• Military and medical equipment lighting
• Sensor integrated lighting modules

Procurement Notes

Verify the specific ordering suffix (PWP vs PWPR) to ensure correct packaging type, as tube and cut tape variants may differ in handling requirements. Confirm that the 14-pin TSSOP footprint matches your PCB layout constraints. Ensure the external sensor resistor values align with the required LED current settings defined in the official datasheet to maintain proper regulation.

Selection Notes

Select this component when designing circuits requiring high brightness LED driving with a single-stage boost topology. It is suitable for applications needing up to 3 A output current and inputs ranging up to 18 V. Consider the thermal performance of the TSSOP package if operating near the upper limits of the temperature range. Verify compatibility with available dimming interfaces before finalizing the design.

Part Context

This part belongs to Texas Instruments' family of high-power DC/DC boost converters designed specifically for LED applications. It complements other devices like the TPS61175 and TPS62110 by offering cross-functional capabilities across various lighting sectors. The series emphasizes improved LED circuit design through smaller voltage references and energy-efficient operation.

Replacement Considerations

The TPS61500PWP is parametrically equivalent to the TPS61500PWPR, differing primarily in packaging format (tube versus cut tape). No alternative functional substitutes are explicitly documented in the provided source material.
