(2) Power rating at a specific ambient temperature TA should be determined with a junction temperature of 150°C. This is the point where distortion starts to substantially increase. See the Power Dissipation Estimate section for more information. 6.4 Thermal Information THERMAL METRIC(1)(2) TPS57060-Q1 UNIT DGQ (MSOP-PowerPAD) DRC (VSON) 10 PINS 10 PINS RθJA Junction-to-ambient thermal resistance 67.4 45.2 °C/W RθJC(top) Junction-to-case (top) thermal resistance 46.7 52.1 °C/W RθJB Junction-to-board thermal resistance 38.4 20.6 °C/W ψJT Junction-to-top characterization parameter 1.9 0.9 °C/W ψJB Junction-to-board characterization parameter 38.1 20.8 °C/W RθJC(bot) Junction-to-case (bottom) thermal resistance 15.9 5.2 °C/W 6.5 Electrical Characteristics TJ = –40°C to 150°C, VIN = 3.5 to 60 V (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT SUPPLY VOLTAGE (VIN PIN) Operating input voltage 3.5 60 V Internal undervoltage lockout threshold No voltage hysteresis, rising and falling 2.5 V Shutdown supply current EN = 0 V, 25°C, 3.5 V ≤ VIN ≤ 60 V 1.3 4 μA EN = 0 V, 125°C, 3.5 V ≤ VIN ≤ 60 V 1.9 6.5 Operating: nonswitching supply current VSENSE = 0.83 V, VIN = 12 V, 25°C 116 136 μA ENABLE AND UVLO (EN PIN) Enable threshold voltage No voltage hysteresis, rising and falling, 25°C 1.15 1.25 1.36 V Input current Enable threshold +50 mV –3.8 μA Enable threshold –50 mV –0.9 Hysteresis current –2.9 μA VOLTAGE REFERENCE Voltage reference 0.792 0.8 0.808 V HIGH-SIDE MOSFET On-resistance VIN = 3.5 V, BOOT-PH = 3 V 300 m Ω VIN = 12 V, BOOT-PH = 6 V 200 410 ERROR AMPLIFIER Input current 50 nA Error amplifier transconductance (gM) –2 μA < ICOMP < 2 μA, VCOMP = 1 V 97 μMhos Error amplifier transconductance (gM) during slow start –2 μA < ICOMP < 2 μA, VCOMP = 1 V, VVSENSE = 0.4 V 26 μMhos Error amplifier dc gain VVSENSE = 0.8 V 10,000 V/V Error amplifier bandwidth 2700 kHz Error amplifier source/sink V(COMP) = 1 V, 100 mV overdrive ±7 μA COMP to switch current transconductance 1.9 A/V |
