TPS92601QPWPRQ1

The TPS92601QPWPRQ1 is a 1-channel high-side current sense switching mode LED Driver with full protection and diagnostics. The base of each independent driver is a peak-current-mode boost controller. Each controller has two independent feedback loops, a current-feedback loop with a high-side current-sensing shunt and a voltage-feedback loop with an external resistor-divider network. The controller delivers a constant output voltage or a constant output current. The connected load determines whether the device regulates a constant output current (if the circuit reaches the current set-point earlier than voltage set-point) or a constant output voltage (if the circuit reaches the voltage set-point is reached first, for example, in an open-load condition). Each controller supports all typical topologies such as boost, boost-to-battery, SEPIC or flyback.
