The TPS92690/90Q1 is a high voltage, low-side NFET controller with an adjustable output current sense resistor voltage. Ideal for LED drivers, it contains all of the features needed to implement current regulators based on boost, SEPIC, flyback, and Cuk topologies.
Output current regulation is based on peak current-mode control supervised by a control loop. This methodology eases the design of loop compensation while providing inherent input voltage feed-forward compensation. The TPS92690/90Q1 includes a high-voltage start-up regulator that operates over a wide input range of 4.5V to 75V. The PWM controller is designed for high speed capability including an oscillator frequency range up to 2.0 MHz. The TPS92690/90Q1 includes an error amplifier, precision reference, cycle-by-cycle current limit, and thermal shutdown.
The TPS92690Q1 is AEC-Q100 grade 1 qualified.
