TPS92691QPWPRQ1 Multi-Topology LED Driver With Rail-To-Rail Current Sense Amplifier

TPS92691QPWPRQ1 Multi-Topology LED Driver With Rail-To-Rail Current Sense Amplifier

Product Description Of TPS92691QPWPRQ1

TPS92691QPWPRQ1 is a versatile LED controller that can support a range of step-up or step-down driver topologies. The device implements a fixed-frequency peak current mode control technique with programmable switching frequency,slope compensation,and soft-start timing. It incorporates a high voltage(65-V) rail-to-rail current sense amplifier that can directly measure LED current using either a high-side or a low-side series sense resistor. The amplifier is designed to achieve low input offset voltage and attain better than ±3% LED current accuracy over junction temperature range of 25℃ to 140℃ and output common-mode voltage range of 0 to 60 V.
