(2) Level listed above is the passing level per ANSI, ESDA, and JEDEC JS-001. JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (3) Level listed above is the passing level per EIA-JEDEC JESD22-C101. JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. (4) The machine model is a 200-pF capacitor discharged directly into each pin. 8.2 ESD Ratings VALUE UNIT VESD (1) Human body model (HBM) ESD stress voltage(2) ±2000 V Charge device model (CDM) ESD stress voltage(3) ±1000 Machine model (MM) ESD stress voltage(4) ±200 V (1) Operation above 4.8V input voltage for extended periods may affect device reliability. (2) In certain applications larger capacitor values can be tolerable, see Output Capacitor Selection section for more details. 8.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT VIN Input voltage range 2.3 4.8(1) V IO Output current range TPS82671 to TPS826765 0 600 mA Additional output capacitance (PFM/PWM operation)(2) TPS82670 to TPS82676 TPS826711, TPS826716, TPS826721, TPS826765, TPS8267195 0 2.5 µF TPS82677 0 4 µF Additional output capacitance (PWM operation)(2) 0 7 µF TA Ambient temperature –40 +85 °C TJ Operating junction temperature –40 +125 °C (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. 8.4 Thermal Information THERMAL METRIC(1) TPS8267x UNIT SIP 8 PINS RθJA Junction-to-ambient (top) thermal resistance 125 °C/W Junction-to-ambient (bottom) thermal resistance 70 RθJCtop Junction-to-case (top) thermal resistance - RθJB Junction-to-board thermal resistance - ψJT Junction-to-top characterization parameter - ψJB Junction-to-board characterization parameter - RθJCbot Junction-to-case (bottom) thermal resistance - 8.5 Electrical Characteristics Minimum and maximum values are at VIN = 2.3V to 5.5V, VOUT = 1.8V, EN = 1.8V, AUTO mode and TA = –40°C to 85°C; Circuit of Parameter Measurement Information section (unless otherwise noted).
