3 / 29 page LP38851 www.ti.com SNVS492C – JUNE 2007 – REVISED APRIL 2013 PIN DESCRIPTIONS (continued) SFM PFM SO PowerPad Pin Pin Description Pin # Pin # Pin # Symbol The SO PowerPad DAP is a thermal connection only that is physically attached to the backside of the die, and used as a - - DAP DAP thermal heat-sink connection. See APPLICATION INFORMATION for details. 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) Storage Temperature Range −65°C to +150°C Lead Temperature Soldering, 5 seconds 260°C ESD Rating Human Body Model (2) ±2 kV Power Dissipation (3) Internally Limited VIN Supply Voltage (Survival) −0.3V to +6.0V VBIAS Supply Voltage (Survival) −0.3V to +6.0V VSS SoftStart Voltage (Survival) −0.3V to +6.0V VOUT Voltage (Survival) −0.3V to +6.0V IOUT Current (Survival) Internally Limited Junction Temperature −40°C to +150°C (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 does not ensure specific performance limits. For specifications and conditions, see the Electrical Characteristics. (2) The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin. Test method is per JESD22-A114. (3) Device power dissipation must be de-rated based on device power dissipation (PD), ambient temperature (TA), and package junction to ambient thermal resistance ( θJA). Additional heat-sinking may be required to ensure that the device junction temperature (TJ) does not exceed the maximum operating rating. See APPLICATION INFORMATION for details. OPERATING RATINGS (1) VIN Supply Voltage (VOUT + VDO) to VBIAS 0.8V ≤ VOUT ≤ 1.2V 3.0V to 5.5V VBIAS Supply Voltage 1.2V < VOUT ≤ 1.8V 4.5V to 5.5V VEN Voltage 0.0V to VBIAS IOUT 0 mA to 800 mA Junction Temperature Range (2) −40°C to +125°C (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 does not ensure specific performance limits. For specifications and conditions, see the Electrical Characteristics. (2) Device power dissipation must be de-rated based on device power dissipation (PD), ambient temperature (TA), and package junction to ambient thermal resistance ( θJA). Additional heat-sinking may be required to ensure that the device junction temperature (TJ) does not exceed the maximum operating rating. See APPLICATION INFORMATION for details.
