TPS61150DRCRG4

Overview

The TPS61150DRCRG4 is a dual-output boost converter IC designed for white LED backlight applications. It operates with an input voltage range of 2.5 V to 6 V and delivers up to 700 mA output current per channel. The device features a fixed switching frequency of 1.2 MHz and supports PWM dimming control. It provides a maximum output voltage of 27 V and includes an integrated switch within a VSON-10 package. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture enabling independent control of two LED strings using a single inductor
• Integrated high-side power switch reduces external component count and board space requirements
• Supports wide-range PWM dimming for precise brightness control in display backlight systems

Applications

• Mobile phone LCD backlighting
• Tablet computer display illumination
• Portable media player backlight drivers

Procurement Notes

Verify the G4 suffix indicates lead-free and RoHS compliance status according to Texas Instruments documentation. Confirm the VSON-10 package dimensions match PCB footprint requirements. Ensure thermal management strategies align with the specified operating temperature range. Check for moisture sensitivity level requirements during storage and reflow processes.

Selection Notes

Select this component when dual LED strings require independent current regulation from a single boost stage. Consider the 1.2 MHz frequency for balancing efficiency and passive component size. Evaluate input voltage compatibility with battery types ranging from 2.5 V to 6 V. Assess thermal performance capabilities within the constrained VSON-10 package for high-current applications.

Part Context

This part belongs to the TPS61150 series of dual-output boost converters. It is specifically engineered for portable electronics requiring efficient white LED driving.
