Overview
The TPS61150DRCR is a dual-output boost white LED driver IC from Texas Instruments, housed in a VSON-10 package. 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 output voltages up to 27 V. Designed for surface-mount installation, it functions within a temperature range of -40°C to +85°C.
Feature Summary
- Dual-channel architecture utilizing a single inductor for efficient space-constrained designs
- Integrated power switch eliminates external component requirements
- Supports PWM dimming control for precise brightness adjustment
Applications
- White LED backlighting for mobile devices
- Portable electronic display illumination
- Compact lighting systems requiring dual-zone control
Procurement Notes
Verify the specific suffix 'CR' indicates cut-tape packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference datasheet revisions to guarantee compatibility with existing design specifications.
Selection Notes
Select this component for applications requiring dual independent LED channels driven by a single inductor. The 1.2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the required output voltage does not exceed the 27 V limit and that the input supply remains within the 2.5 V to 6 V operational window.
Part Context
This part belongs to the TPS61150 series of dual-output boost converters specifically engineered for white LED drivers. The DRCR variant denotes the VSON-10 package with cut-tape reel packaging. It serves as a compact solution for replacing discrete solutions in portable electronics where board space is limited.
Replacement Considerations
The TPS61150DRCT is a compatible alternative differing primarily in packaging format (tray vs. cut tape). The TPS61150ADRCR represents an advanced version within the same family; verify pinout and electrical parameter compatibility before substitution.
