2 / 30 page TPS62040 TPS62042, TPS62043 TPS62044, TPS62046 SLVS463B − JUNE 2003 − REVISED OCTOBER 2005 www.ti.com 2 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range unless otherwise noted(1) UNITS Supply voltage VIN (2) −0.3 V to 7 V Voltages on EN, MODE, FB, SW(2) −0.3 V to VCC +0.3 V Continuous power dissipation See Dissipation Rating Table Operating junction temperature range −40°C to 150°C Storage temperature range −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.
