3 / 27 page LM26001B www.ti.com SNVS491B – MAY 2007 – REVISED APRIL 2013 Absolute Maximum Ratings (1) Voltages from the indicated pins to GND: VIN -0.3V to 20V SW(2) -0.5V to 20V VDD -0.3V to 7V VBIAS -0.3V to 10V FB -0.3V to 6V BOOT SW-0.3V to SW+7V PGOOD -0.3V to 7V FREQ -0.3V to 7V SYNC -0.3V to 7V EN -0.3V to 20V FPWM -0.3V to 7V SS -0.3V to 7V Storage Temperature -65°C to +150°C Power Dissipation(3) 2.6 W Vapor Phase (70s) 215°C Recommended Lead Temperature Infrared (15s) 220°C Machine Model 200V ESD Susceptibility(4) Human Body Model 2KV Charged Device Model 1kV (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the Electrical Characteristics. (2) The absolute maximum specification applies to DC voltage. An extended negative voltage limit of -2V applies for a pulse of up to 1µs, and -1V for a pulse of up to 20µs. (3) 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. The maximum allowable power dissipation at any ambient temperature is calculated using: PD_MAX = (TJ_MAX - TA) /θJA. The maximum power dissipation of 2.6W is determined using TA = 25°C, θJA = 38°C/W, and TJ_MAX = 125°C. (4) The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. The machine model is a 200pF capacitor discharged directly into each pin. The charged device model is per JESD22-C101-C. Operating Ratings (1) Operating Junction Temp. −40°C to 125°C Supply Voltage(2) 3.0V to 18V (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the Electrical Characteristics. (2) Below 4.0V input, power dissipation may increase due to increased RDS(ON). Therefore, a minimum input voltage of 4.0V is required to operate continuously within specification. A minimum of 3.9V (typical) is also required for startup.
