The TPS4000x controllers implement a closed-loop soft start function. Startup ramp time is set by a single external capacitor connected to the SS/SD pin. The SS/SD pin is also used for shutdown. ORDERING INFORMATION PACKAGED DEVICES MSOP(2) (DGQ) APPLICATION TA FREQUENCY SOURCE ONLY SOURCE/SINK WITH PREBIAS(3) SOURCE/SINK(3) −40 °C to 85°C 300 kHz TPS40000DGQ TPS40001DGQ TPS40004DGQ −40 °C to 85°C 600 kHz TPS40002DGQ TPS40003DGQ TPS40005DGQ (2) The DGQ package is available taped and reeled. Add R suffix to device type (e.g. TPS40000DGQR) to order quantities of 2,500 devices per reel and 80 units per tube. (3) See Application Information section, p. 8. ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range unless otherwise noted(1) TPS4000x UNIT BOOT VSW + 6.5 COMP, FB, ILIM, SS/SD −0.3 to 6 Input voltage range, VIN SW −0.7 to 10.5 V Input voltage range, VIN SWT (SW transient < 50 ns) −2.5 V VDD 6 Operating junction temperature range, TJ −40 to 150 Storage temperature, Tstg −55 to 150 °C Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds 260 C (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.
