Overview
The TPS61166DSKR is a boost converter LED driver from Texas Instruments, designed to drive up to five white LEDs in series. It features an integrated 20-V rated switch FET and power diode. The device operates with an IC supply range of 2.5 V to 6 V and a power stage input range of 4.5 V to 10 V. It supports PWM dimming and includes fast burst mode dimming capabilities for high-contrast applications.
Feature Summary
- Integrates a 20-V rated switch FET and power diode for compact design
- Supports driving up to five LEDs in series configuration
- Enables high-contrast lighting via fast burst mode dimming
Applications
- White LED backlighting systems
- Portable electronic device illumination
- General-purpose LED lighting drivers
Procurement Notes
Verify the specific suffix 'DSKR' against the official Texas Instruments datasheet to confirm package type and tape-and-reel specifications. Ensure the application circuit matches the required input voltage ranges (2.5 V–6 V IC supply) and output requirements for series LED strings. Cross-reference the part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a single-channel boost solution is needed for multiple series-connected LEDs. It is suitable for designs requiring an integrated power stage to minimize external component count. Consider the 20-V rating for headroom in LED string voltage requirements. Evaluate thermal performance based on the WSON EP package if operating near maximum current limits.
Part Context
This part belongs to the TPS6116x family of LED drivers. It shares functional similarities with other members like the TPS61169 but differs in specific ratings and integration levels. The TPS61166 specifically targets applications requiring higher voltage capability for series LED strings compared to lower-voltage counterparts.
Replacement Considerations
Check for direct pin-to-pin replacements within the TPS6116x family, such as the TPS61166DSKT. Verify that alternative parts support the same 20-V switch rating and fast burst mode dimming functionality before substitution.
