Overview
The TPS61043DRBR is a constant current LED driver IC from Texas Instruments, designed to power up to four LEDs in series. It operates within an input voltage range of 1.8 V to 6 V and features an internal 30-V switch. The device achieves up to 85% efficiency and supports precise brightness control via PWM. It utilizes an external sense resistor for LED current setting and is housed in an 8-SON package.
Feature Summary
- Provides constant current output suitable for driving white LEDs or similar loads
- Enables precise brightness adjustment through pulse-width modulation (PWM) control
- Integrates a high-frequency boost converter topology with an internal 30-V switch
Applications
- Portable LED lighting systems
- Battery-powered illumination devices
- White LED backlighting applications
Procurement Notes
Verify the specific suffix DRBR against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Ensure compatibility with the intended PCB footprint, as the component uses an 8-SON package. Cross-reference the revision level to guarantee alignment with design specifications before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring efficient constant current drive for multiple series-connected LEDs. It is appropriate for applications needing wide input voltage tolerance and high efficiency. Consider the 8-SON package size for space-constrained designs requiring integrated switching capabilities without external power switches.
Part Context
This part belongs to the TPS6104x family of switch boost converters by Texas Instruments. These devices are categorized under PMIC - Power Management ICs, specifically within the DC-DC Switching Regulators subcategory. The TPS61043 variant focuses on constant current regulation for LED loads rather than adjustable voltage outputs found in other family members.
Replacement Considerations
Publicly confirmed substitute part numbers for the TPS61043DRBR were not identified in the provided documentation. Verify functional equivalence with other TPS6104x variants only if datasheet parameters match exactly.
