TPS65137ADSCR

Overview

The TPS65137ADSCR is an LED lighting driver IC manufactured by Texas Instruments. It features a dual positive and negative output topology combining boost and buck converters within a single WSON-10 package. The device operates on a supply voltage range of 2.5 V to 4.8 V with an adjustable output voltage capability. It supports a maximum output current of 200 mA and functions at a switching frequency of 1.6 MHz. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates dual positive and negative outputs using combined boost and buck topologies
• Designed specifically for LED lighting applications
• Operates with adjustable output voltage settings

Applications

• LED lighting systems requiring dual polarity power supplies

Procurement Notes

Verify the specific suffix 'ASDSCR' against the manufacturer's official documentation to confirm exact packaging, tape-and-reel specifications, and environmental compliance status. Ensure the ordering part number matches the required temperature rating and package variant before procurement.

Selection Notes

Select this component when designing LED drivers that require both positive and negative rails from a low-voltage input source. Consider the 200 mA current limit and 1.6 MHz switching frequency for thermal management and EMI constraints in compact WSON-10 footprints.

Part Context
