TPS92515x/TPS92515x-Q1 2A LED Drivers

Texas Instruments TPS92515x/TPS92515x-Q1 2A LED Drivers are compact monolithic switching regulators integrating a low resistance N-Channel MOSFET. The devices are intended for high-brightness LED lighting applications where efficiency, high bandwidth, PWM and/or analog dimming, and small size are important. The regulator operates using a constant off-time, peak current control. The operation is simple: after an off-time based on the output voltage, an on-time begins. The on-time ends once the inductor peak current threshold is reached. The TPS92515x/TPS92515x-Q1 devices can be configured to maintain a constant peak-to-peak ripple during the ON and OFF periods of a shunt FET dimming cycle. This feature is ideal for maintaining a linear response across the entire shunt FET dimming range. The TPS92515 and TPS92515-Q1 devices have an operational input range up to 42V. The TPS92515HV and TPS92515HV-Q1 offer high-voltage options with an input range up to 65V. The Texas Instruments TPS92515x-Q1 devices are AEC-Q100 qualified for automotive applications.
