3 / 26 page LM3500 www.ti.com SNVS231G – AUGUST 2003 – REVISED MAY 2013 SHDN(pin A2): Shutdown control pin. Disable the device with a voltage less than 0.3V and enable the device with a voltage greater than 1.1V. The white LED current can be controlled using a PWM signal at this pin. There is an internal pull down on the SHDN pin, the device is in a normally off state. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) VIN −0.3V to 7.5V VOUT (LM3500-16) (3) −0.3V to 16V VOUT (LM3500-21) (3) −0.3V to 21V VSW (3) −0.3V to VOUT+0.3V FB, SHDN, and NC Voltages −0.3V to 7.5V Maximum Junction Temperature 150°C Lead Temperature(4) 300°C ESD Ratings(5) Human Body Model 2kV Machine Model 200V (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 specified. For specified specifications and test conditions, see the Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) This condition applies if VIN < VOUT. If VIN > VOUT, a voltage greater than VIN + 0.3V should not be applied to the VOUT or VSW pins. (4) For more detailed soldering information and specifications, please refer to Texas Instruments Application Note 1112: DSBGA Wafer Level Chip Scale Package (5) 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 200 pF capacitor discharged directly into each pin. Operating Conditions Ambient Temperature(1) −40°C to +85°C Junction Temperature −40°C to +125°C Supply Voltage 2.7V to 7V (1) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX-OP = 125ºC), the maximum power dissipation of the device in the application (PD-MAX), and the junction-to ambient thermal resistance of the part/package in the application ( θJA), as given by the following equation: TA-MAX = TJ-MAX-OP – (θJA × PD-MAX). Thermal Properties Junction to Ambient Thermal Resistance ( θJA) (1) 75°C/W (1) Junction-to-ambient thermal resistance ( θJA) is highly application and board-layout dependent. The 75ºC/W figure provided was measured on a 4-layer test board conforming to JEDEC standards. In applications where high maximum power dissipation exists, special care must be paid to thermal dissipation issues when designing the board layout.
