TEXAS INSTRUMENTS  TPS92601QPWPRQ1  发光二极管驱动器, 1输出, 升压, 反激, SEPIC, 4V-40V输入, 600kHz开关, 75V/1.5A输出, HTSSOP-20

The 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.
