2 / 25 page www.ti.com ABSOLUTE MAXIMUM RATINGS RECOMMENDED OPERATING CONDITIONS ELECTRICAL CHARACTERISTICS TPS61090 TPS61091, TPS61092 SLVS484A – JUNE 2003 – REVISED APRIL 2004 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. AVAILABLE OUTPUT VOLTAGE OPTIONS(1) OUTPUT VOLTAGE TA PACKAGE Part Number(2) DC/DC Adjustable 16-Pin QFN 4x4mm TPS61090RSA 40 °C to 85°C 3.3 V 16-Pin QFN 4x4mm TPS61091RSA 5 V 16-Pin QFN 4x4mm TPS61092RSA (1) Contact the factory to check availability of other fixed output voltage versions. (2) The RSA package is available taped and reeled. Add R suffix to device type (e.g., TPS61090RSAR) to order quantities of 3000 devices per reel. over operating free-air temperature range (unless otherwise noted)(1) TPS6109x Input voltage range on LBI -0.3 V to 3.6 V Input voltage range on SW, VOUT, LBO, VBAT, SYNC, EN, FB -0.3 V to 7 V Operating free air temperature range TA -40 °C to 85°C Maximum junction temperature TJ 150 °C Storage temperature range Tstg -65 °C to 150°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.
