Overview
The TPS923652DRRR is a non-synchronous boost or buck-boost LED driver IC from Texas Instruments. It supports an input voltage range of 4.5 V to 65 V and delivers up to 2 A output current. The device operates at a programmable switching frequency between 100 kHz and 2.2 MHz, with an output voltage capability of 0 V to 63 V. It is housed in a WSON-12 package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a high-side switching FET for compact design
- Supports analog, PWM, hybrid, and flexible dimming methods
- Includes cycle-by-cycle over-current protection and thermal shutdown
- Features open and short LED detection capabilities
Applications
- Automotive interior lighting systems
- General solid-state lighting applications
- Industrial LED illumination modules
Procurement Notes
Verify the specific suffix DRRR against official Texas Instruments documentation to confirm the reel quantity and tape specifications. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to confirm compatibility with your design constraints before finalizing procurement orders.
Selection Notes
Select this component when a single-channel driver with up to 2 A capacity is required for boost or buck-boost topologies. It is suitable for designs needing wide input voltage ranges and integrated fault protection. Consider the WSON-12 package size and thermal performance requirements relative to other series members like the TPS923655.
Part Context
This part belongs to the TPS92365x family of automotive-grade LED drivers designed for robust operation in demanding environments. It shares functional similarities with the TPS923655 but offers lower current capacity. The series emphasizes integration and protection features for reliable LED control in vehicle and industrial settings.
Replacement Considerations
The TPS923655DRRR serves as a higher-current alternative within the same family. Verify pinout compatibility and thermal dissipation differences when substituting. No direct cross-model replacements are confirmed in public data.
