Maximum ambient temperature (TA(max)) is dependent on the maximum operating junction temperature (TJ(max)), the maximum power dissipation of the device in the application (PD(max)), and the junction-to-ambient thermal resistance of the part/package in the application (RθJA), as given by the following equation: TA(max) = TJ(max) – (RθJA × PD(max)). (2) The minimum required supply voltage for startup is 2.05 V. The part is functional down to the falling undervoltage lockout (UVL) threshold. (3) For a voltage difference between minimum VIN and VOUT of ≥ 1 V (4) Typical value applies for TA = 25°C, maximum value applies for TJ ≤ 125°C, PCB layout must support proper thermal performance. 7.3 Recommended Operating Conditions over operating junction temperature range (unless otherwise noted) (1) MIN NOM MAX UNIT Supply voltage VIN (2) 2.05 6 V Effective inductance 2.2 μH Effective capacitance 2 4.7 μF Recommended minimum supply voltage VOUT ≤ VIN –1 V (3) 500 mA maximum IOUT (4) 3 3.6 V 350 mA maximum IOUT (4) 2.5 2.7 VOUT ≤ 1.8 V 60 mA maximum output current(4) 2.05 Operating junction temperature, TJ –40 125 °C (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953. 7.4 Thermal Information THERMAL METRIC(1) TPS6223x UNIT DRY (USON) 6 PINS RθJA Junction-to-ambient thermal resistance 294.5 °C/W RθJC(top) Junction-to-case (top) thermal resistance 166.5 °C/W RθJB Junction-to-board thermal resistance 166.1 °C/W ψJT Junction-to-top characterization parameter 27.3 °C/W ψJB Junction-to-board characterization parameter 159.9 °C/W RθJC(bot) Junction-to-case (bottom) thermal resistance — °C/W |
