Overview
The TPS61150ADRCTG4 is a dual-output boost DC-DC converter designed for white LED backlighting applications. It integrates two independent current sources capable of delivering up to 700 mA per channel, supporting configurations such as 14-segment displays. The device operates within an input voltage range of 2.5 V to 6 V and can generate output voltages up to 27 V. It functions at a switching frequency of 1.2 MHz and is housed in a compact VSON-10 package. The component supports operation across a temperature range of -40°C to +85°C.
Feature Summary
- Dual independent current sources for flexible LED string configurations
- Integrated high-frequency switching for compact external component sizing
- Supports PWM dimming control for brightness adjustment
Applications
- White LED backlight drivers for mobile devices
- Backlight drivers for LCD panels with multiple LED strings
- Power supply for 14-segment display applications
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as defined by Texas Instruments. Confirm the package marking matches the VSON-10 physical dimensions. Ensure the ordering part number aligns with the required tape-and-reel quantity specifications provided in the official manufacturer documentation.
Selection Notes
Select this component when dual-channel LED driving is required from a single power stage. It is suitable for systems needing an input voltage between 2.5 V and 6 V. Consider the 1.2 MHz frequency for balancing EMI and passive component size. Verify that the maximum output voltage requirement does not exceed 27 V for the intended LED string configuration.
Part Context
This part belongs to the TPS61150 series of LED lighting driver ICs. It is specifically engineered for portable electronics requiring efficient backlighting solutions. The device simplifies design by integrating the boost converter and current regulation into a single small footprint, reducing board space compared to discrete solutions.
Replacement Considerations
The TPS61150DRCT is a related variant within the same family. Verify if the non-A grade version meets the specific electrical tolerance requirements for the application.
