Add T suffix (TPS61043DRBT) to order quantities of 250 devices per reel. over operating free-air temperature range (unless otherwise noted)(1) TPS61043 Supply Voltages, v(VIN) (2) -0.3 V to 7 V Voltages, V(Rs), V(CTRL), V(FB) -0.3 V to Vin + 0.3 V Voltages, V(SW), V(LED) (2) 30 V Voltage, V(OVP) 30 V Continuous power dissipation See Dissipation Rating Table Operating junction temperature range -40 °C to 150°C Storage temperature range, TSTG -65 °C to 150°C Lead temperature (soldering, 10 sec) 260 °C (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to network ground terminal.
