The TPS92640PWP/NOPB from Texas Instruments is a high-voltage, synchronous NFET controller designed for buck-current regulators. It features a wide input voltage range from 7 V to 85 V and can deliver up to 5 A of output current.
This LED driver controller supports precision dimming through both analog (500:1) and PWM (2500:1 to 20000:1) methods, offering design flexibility. It operates within a temperature range of -40°C to 125°C and includes essential protection features such as Over Voltage Protection (OVP) and thermal shutdown.
The device utilizes a controlled on-time architecture for valley current-mode operation, which simplifies loop compensation and maintains a nearly constant switching frequency. It is housed in a 14-HTSSOP package suitable for surface mounting.
Key electrical specifications include a typical quiescent current of 2 mA and a switching frequency of 1 MHz. The TPS92640PWP/NOPB is well-suited for automotive applications requiring precise LED illumination control.
