5 / 14 page Electrical Characteristics AVIN = PVIN = 5V unless otherwise indicated under the Conditions column. Limits in standard type are for T J = 25˚C only; limits in boldface type apply over the junction temperature (TJ) range of -40˚C to +125˚C. Minimum and Maximum limits are guaranteed through test, design, or statistical correlation. Typical values represent the most likely parametric norm at T J = 25˚C, and are provided for reference purposes only. (Continued) Symbol Parameter Conditions Min Typ Max Units D range Duty Cycle Range 0 100 % ENABLE CONTROL 4 V IH EN Pin Minimum High Input 75 %of AVIN V IL EN Pin Maximum Low Input 25 %of AVIN I EN EN Pin Pullup Current EN = 0V 1.2 µA THERMAL CONTROLS T SD T J for Thermal Shutdown 165 ˚C T SD-HYS Hysteresis for Thermal Shutdown 10 ˚C Note 1: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Range indicates conditions for which the device is intended to be functional, but does not guarantee specfic performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. Note 2: Human body model: 1.5k Ω in series with 100pF. SW and PVIN pins are derated to 1.5kV Note 3: VOUT measured in a non-switching, closed-loop configuration at the SNS pin. Note 4: The enable pin is internally pulled up, so the LM2852 is automatically enabled unless an external enable voltage is applied. www.national.com 5 |
