6 / 17 page Electrical Characteristics (Continued) Specifications in standard type face are for T J = 25˚C and those with boldface type apply over the full Operating Tempera- ture Range (T J = −40˚C to +125˚C) Unless otherwise specified. VIN = 5V and IL = 0A, unless otherwise specified. Symbol Parameter Conditions Min (Note 4) Typ (Note 5) Max (Note 4) Units Th SHDN1 Buck SHDN Threshold Output High 1.37 2 V Output Low 0.8 1.35 Th SHDN2 Boost SHDN Threshold Output High 1.37 2 V Output Low 0.8 1.35 I SS1 Buck Soft Start Pin Current 6 9.5 12 µA I SS2 Boost Soft Start Pin Current 15 19 22 µA UVP On Threshold 3.35 3.8 4.0 V Off Threshold 3.10 3.6 3.9 θ JA Thermal Resistance (Note 9) TSSOP, package only 115 ˚C/W Note 1: Absolute maximum ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions for which the device is intended to be functional, but device parameter specifications may not be guaranteed. For guaranteed specifications and test conditions, see the Electrical Characteristics. Note 2: The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. See the Electrical Characteristics table for the thermal resistance. The maximum allowable power dissipation at any ambient temperature is calculated using: PD (MAX) = (TJ(MAX) −TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Note 3: The human body model is a 100 pF capacitor discharged through a 1.5k Ω resistor into each pin. The machine model is a 200pF capacitor discharged directly into each pin. Note 4: All limits guaranteed at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits are 100% tested or guaranteed through statistical analysis. All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). Note 5: Typical numbers are at 25˚C and represent the most likely norm. Note 6: Duty cycle affects current limit due to ramp generator. Note 7: Current limit at 95% duty cycle. See TYPICAL PERFORMANCE section for Switch Current Limit vs. VIN Note 8: Bias current flows into FB pin. Note 9: Refer to National’s packaging website for more detailed thermal information and mounting techniques for the TSSOP package. www.national.com 6 |
