TPS92640PWPR Description

Short technical summary and product information.

The TPS92640PWPR from Texas Instruments is a high-voltage, synchronous NFET controller for buck-current regulators. It is designed for precision dimming LED driver applications.

 

This device operates with an input voltage ranging from 7 V to 85 V and can provide an output voltage up to 83 V, with a maximum output current of 5 A. It features OVP (Overvoltage Protection) and thermal shutdown for reliability. The dimming capabilities include Analog dimming with a range of 500:1, standard PWM dimming at 2500:1, and Shunt FET PWM dimming up to 20000:1.

 

The TPS92640PWPR utilizes a controlled on-time architecture for valley current-mode operation, which simplifies loop compensation and maintains a nearly constant switching frequency. It includes integrated MOSFET gate drivers capable of 2-Ω, 1-A peak performance. A precision voltage reference of 3 V ±2% is also integrated.

 

Packaged in an HTSSOP (PWP) 14-lead package measuring 5 mm × 6.4 mm with an area of 32 mm², this controller is suitable for various illumination and automotive LED driver applications. The operating temperature range is from -40 °C to 125 °C.
