TPS92512DGQR Description

Short technical summary and product information.

The Texas Instruments TPS92512DGQR is a 2.5A step-down (buck) current regulator with an integrated MOSFET, designed to drive high-current LEDs. It supports an input voltage range from 4.5V to 42V and operates at a user-selectable fixed frequency up to 2MHz, utilizing peak-current mode control for excellent line and load regulation.

 

Key electrical features include a ±5% LED current accuracy, an adjustable voltage reference from 0V to 300mV, and an integrated 200-mΩ high-side MOSFET. The device also incorporates dedicated inputs for analog and pulse width modulation (PWM) dimming, allowing for precise brightness control. Protection features include adjustable undervoltage-lock-out, overcurrent protection, and overtemperature protection.

 

The TPS92512DGQR is supplied in a 10-HVSSOP package suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). This LED driver is well-suited for various lighting applications requiring efficient and accurate current regulation.
