TPS92512HVDGQR

LED Driver IC Overview

The TPS92512HVDGQR is a single-channel LED lighting driver IC from the TPS92512HV series, manufactured by Texas Instruments. It utilizes a buck topology to regulate current for LED loads. The device supports an input voltage range of 4.5 V to 60 V and delivers a maximum output current of 2.5 A. It operates within a switching frequency range of 100 kHz to 2 MHz and can handle output voltages up to 65 V. The component is housed in a 10-lead MSOP-PowerPad package and functions reliably across an operating temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Integrates a high-side N-channel MOSFET switch to minimize external component count.
• Supports both analog and pulse-width modulation (PWM) dimming methods for brightness control.
• Includes thermal protection circuitry to safeguard the device during overtemperature conditions.

LED Driver IC Applications

• General LED lighting systems
• Automotive interior illumination
• Industrial LED drivers

LED Driver IC Procurement Notes

Verify the specific suffix 'DGQR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the application design accommodates the specified 60 V input limit and 2.5 A current capability. Ensure thermal management strategies align with the MSOP-PowerPad package's heat dissipation characteristics under expected load conditions.

LED Driver IC Selection Notes

Select this component when a single-channel buck converter with integrated power switches is required for high-voltage LED strings. It is suitable for designs needing adjustable switching frequencies to optimize efficiency or reduce electromagnetic interference. Consider this part for applications requiring robust thermal protection and flexible dimming interfaces without external gate drivers.

LED Driver IC Part Context

This device belongs to the TPS92512HV family of LED drivers designed for high-voltage inputs. It shares the same MSOP-PowerPad-10 footprint and core functionality as other members of the series but is distinguished by its specific electrical ratings and packaging variant. The HV designation indicates its capability to handle higher input voltages compared to standard low-voltage counterparts.

LED Driver IC Replacement Considerations

Direct substitutes include TPS92512HVDGQT for cut-tape packaging variations within the same manufacturer line. Other family members like TPS92510DGQ offer similar buck topologies but differ in current ratings and input voltage ranges, requiring circuit re-evaluation before substitution.
