6 / 25 page www.ti.com TPS61010, TPS61011 TPS61012, TPS61013 TPS61014, TPS61015, TPS61016 SLVS314C – SEPTEMBER 2000 – REVISED OCTOBER 2003 The accuracy of the adjustable version is determined by the accuracy of the internal voltage reference, the controller topology, and the accuracy of the external resistor. The reference voltage has an accuracy of ±4% over line, load, and temperature. The controller switches between fixed frequency and pulse-skip mode, depending on load current. This adds an offset to the output voltage that is equivalent to 1% of VO. The tolerance of the resistors in the feedback divider determine the total system accuracy. ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range (unless otherwise noted) (1) UNIT Input voltage range on VBAT, VOUT, SW, EN, LBI, FB, ADEN -0.3 V to 3.6 V SW -0.3 V to 7 V Voltage range on: LBO, COMP 3.6 V Peak current into SW 1300 mA Continuous total power dissipation See Dissipation Rating Table 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 Lead temperature 1,6 mm (1/16 inch) from case for 10s 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.
