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.

(2) The YFF package is available in tape and reel. Add a R suffix (e.g. TPS62620YFFR) to order quantities of 3000 parts. Add a T suffix (e.g. TPS62620YFFT) to order quantities of 250 parts. (3) Internal tap points are available to facilitate output voltages in 25mV increments. over operating free-air temperature range (unless otherwise noted) (1) UNIT Voltage at VIN, SW(2) -0.3 V to 7 V VI Voltage at FB(2) -0.3 V to 3.6 V Voltage at EN, MODE (2) -0.3 V to VI + 0.3 V Power dissipation Internally limited TA Operating temperature range(3) -40°C to 85°C TJ (max) Maximum operating junction temperature 150°C Tstg Storage temperature range -65°C to 150°C Human body model 2 kV ESD rating (4) Charge device model 1 kV Machine model 200 V (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to network ground terminal. (3) 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)), 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 ( θ JA), as given by the following equation: TA(max)= TJ(max)–(θJA X PD(max)). To achieve optimum performance, it is recommended to operate the device with a maximum junction temperature of 105°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 200-pF capacitor discharged directly into each pin. POWER RATING DERATING FACTOR PACKAGE RθJA (2) RθJB (2) TA ≤ 25°C ABOVE TA = 25°C YFF-6 125°C/W 53°C/W 800mW 8mW/°C (1) Maximum power dissipation is a function of TJ(max), θJA and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = [TJ(max)-TA] / θJA. (2) This thermal data is measured with high-K board (4 layers board according to JESD51-7 JEDEC standard). 2 Submit Documentation Feedback Copyright © 2009, Texas Instruments Incorporated Product Folder Link(s): TPS62620 TPS62621 TPS62622 TPS62623 TPS62624 TPS62625 |
