The TPS92515QDGQTQ1 is an internal N-channel MOSFET (monolithic NFET) hysteric control, buck regulator. Hysteretic operation allows a high control bandwidth and is ideal for shunt FET and LED matrix applications (series LED switched network). The high-side differential current sense with low adjustable threshold voltage via a 10:1 divider, provides an excellent method for regulating output current while maintaining high system efficiency.

The TPS92515 family of devices 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.
