The TPS92641PWPT/NOPB from Texas Instruments is a high-voltage, synchronous NFET controller for buck-current regulators. It features an input voltage range from 7 V to 85 V and an output voltage up to 83 V. The device utilizes valley current-mode operation with a controlled on-time architecture, which simplifies loop compensation and maintains a nearly constant switching frequency.
This LED driver controller supports wide dimming ranges, including 500:1 analog dimming, 2500:1 standard PWM dimming, and 20000:1 shunt FET PWM dimming. It includes features such as OVP (Overvoltage Protection), thermal shutdown, input UVLO (Undervoltage Lockout), and a low power shutdown mode. The TPS92641PWPT/NOPB is supplied in a 16-HTSSOP package, suitable for surface mount applications.
Key electrical specifications include a typical quiescent current of 2 mA and a programmable switching frequency of 1 MHz. It also offers an adjustable LED current sense voltage and 1-A peak MOSFET gate drivers. The integrated precision voltage reference is 3 V ±2%. This device is rated for operation within an ambient temperature range of -40°C to 125°C.
