LM2853 数据表(HTML) 4 Page - National Semiconductor (TI) |
4 / 12 page Electrical Characteristics Specifications with standard typeface are for T J = 25˚C, and those in bold face type apply over the full Junction Temperature Range (−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. Unless otherwise specified AVIN = PVIN = 5V. (Continued) Symbol Parameter Conditions Min Typ Max Units THERMAL CONTROLS T SD Thermal Shutdown Threshold 165 ˚C T SD-HYS Hysteresis for Thermal Shutdown 10 ˚C THERMAL RESISTANCE θ JA Junction to Ambient MXA14A 38 ˚C/W 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 specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. Note 2: The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. Test Method is per JESD22-AI14. 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 LM2853 is automatically enabled unless an external enable voltage is applied. www.national.com 4 |
