4 / 11 page Electrical Characteristics (Notes 2, 7) (Continued) and the 2nd copper layer. Ambient temperature in simulation is 22˚C, still air. Power dissipation is 1W. The value of θJA of the LM2754 in LLP-24 could fall in a range as wide as 35oC/W to 150oC/W (if not wider), depending on PWB material, layout, and environmental conditions. In applications where high maximum power dissipation exists (high VIN, high Gain, high IOUT), special care must be paid to thermal dissipation issues. For more information on these topics, please refer to Application Note 1187: Leadless Leadframe Package (LLP) and the Power Efficiency and Power Dissipation section of this datasheet.. Note 7: Min and Max limits are guaranteed by design, test, or statistical analysis. Typical numbers are not guaranteed, but do represent the most likely norm. Note 8: CIN,COUT,C1,C2: Low-ESR Surface-Mount Ceramic Capacitors (MLCCs) used in setting electrical characteristics Note 9: There is a 500k Ω resistor connected internally between each logic pin (EN, T/F, TX, SEL) and GND. Note 10: Headroom Voltage (VHR) is the voltage across the current sinks (VDx) at which the current falls to 95% of the nominal programmed current. VHR is measured from VDx to GND. If the headroom voltage requirement is not met, LED current regulation will be compromised. Note 11: IDx/ISETx Ratio was tested with the Charge Pump in a gain of 1x.
