TPS61055DRCR

Overview

The TPS61055DRCR is a synchronous boost DC-DC converter from Texas Instruments, packaged in a VSON-10 (3x3 mm) surface-mount case. It operates on an input voltage range of 2.5 V to 6 V and delivers up to 500 mA output current. The device supports PWM dimming for LED applications and features a switching frequency selectable between 650 kHz and 1.2 MHz. It functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrated synchronous boost topology for high efficiency
Supports PWM dimming control for LED brightness adjustment
Selectable switching frequency to optimize external component size

Applications

High power white LED drivers
Portable electronic devices requiring step-up conversion
Battery-powered systems with single-cell lithium-ion inputs

Procurement Notes

Verify the specific suffix 'CR' indicates reel packaging when ordering. Confirm moisture sensitivity handling requirements during storage and assembly. Ensure the design accounts for the 3000-unit factory pack quantity if purchasing new reels. Cross-reference the datasheet for thermal performance under maximum load conditions.

Selection Notes

Select this component when a compact solution is needed for driving high-power LEDs from a single-cell battery source. The integrated switch and diode reduce board space compared to discrete solutions. Consider the 500 mA limit for load requirements and the available switching frequencies for filter design.

Part Context

This part belongs to the TPS6105x series of LED lighting driver ICs. It shares architectural similarities with the TPS61052 but is optimized for higher current delivery suitable for white LED arrays. The VSON-10 package provides efficient thermal dissipation for portable applications.

Replacement Considerations

The TPS61052DRCR is a related variant within the same family, though it offers different current capabilities. Verify pin compatibility and electrical specifications before substitution. No other direct public substitute part numbers are confirmed in the provided documentation.
