The TPS92640PWPR/NOPB from Texas Instruments is a high-voltage, synchronous NFET controller for buck-current regulators. It utilizes a valley current-mode operation with a controlled on-time architecture, simplifying loop compensation and maintaining a nearly constant switching frequency. This device is designed for LED driver applications, supporting a wide input voltage range from 7 V to 85 V and an output voltage up to 83 V.
Key electrical specifications include a maximum output current of 5 A and a typical quiescent current of 2 mA. The TPS92640PWPR/NOPB supports both Analog and PWM dimming methods, with wide dimming ranges including 500:1 for Analog, 2500:1 for Standard PWM, and 20000:1 for Shunt FET PWM dimming. It also features over-voltage protection (OVP) and thermal shutdown for reliability.
Packaged in a 14-HTSSOP, this component is designed for surface mount applications. The package dimensions are 14-PowerTSSOP (0.173", 4.40mm Width). It is supplied on a tape and reel with a standard package quantity of 2500 units, a reel diameter of 330 mm, and a reel width of 12.4 mm. The operating temperature range is -40°C to 125°C (TJ).
