Overview
The TPS61151DRCRG4 is a dual-output white LED driver IC from Texas Instruments, utilizing a single inductor boost topology. It integrates two switches capable of delivering up to 700mA output current per channel. The device operates with an input voltage range of 2.5V to 6V and supports PWM dimming for brightness control. Designed for compact applications, it features a VSON-10 package (3x3mm) and functions within a temperature range of -40°C to +85°C. The integrated switching frequency is 1.2MHz, enabling efficient power conversion for high-brightness LED arrays.
Feature Summary
- Dual-channel architecture using a single inductor for space-efficient design
- Integrated high-side switches supporting up to 700mA per output
- Supports PWM dimming for precise brightness regulation
Applications
- White LED backlighting for mobile devices
- High-brightness LED arrays in portable electronics
- Compact lighting solutions requiring dual-channel control
Procurement Notes
Verify the RoHS-compliant suffix 'G4' matches project requirements. Confirm the VSON-10 package dimensions align with PCB layout constraints. Ensure thermal management strategies accommodate the operating temperature range of -40°C to +85°C. Cross-reference the specific revision against the latest Texas Instruments datasheet to confirm pinout and electrical characteristics remain unchanged.
Selection Notes
Select this component when a single-inductor solution is required for dual white LED strings. It is suitable for applications needing independent current control for each channel without increasing bill of materials complexity. Consider the 1.2MHz switching frequency for balancing EMI performance and external component size. Verify that the 6V maximum input voltage covers the system's supply rail under all conditions.
Part Context
This part belongs to the TPS6115x series of dual-output boost converters designed specifically for white LED driving. It shares architectural similarities with the TPS61150 but offers specific packaging and compliance variations. The DRCR variant denotes the tape-and-reel packaging format within the VSON-10 footprint family.
Replacement Considerations
The TPS61151DRCR is a non-RoHS version of the same functional device. The TPS61150DRCR is a similar dual-output driver but may differ in specific electrical parameters or package availability. Verify compatibility before substitution.
