2 / 21 page www.ti.com ABSOLUTE MAXIMUM RATINGS RECOMMENDED OPERATING CONDITIONS TPS54377 SLVS779 – SEPTEMBER 2007 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. ORDERING INFORMATION TJ OUTPUT VOLTAGE PACKAGE PART NUMBER –40 °C to 125°C Adjustable Down to 0.9 V QFN (RHF)(1)(2) TPS54377RHF (1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI website at www.ti.com. (2) The RHF package is available in two different tape and reel quantities. Add an R suffix to the device type (i.e. TPS54377RHFR) for a 3000 piece reel and add a T suffix (TPS54377RHFT) for a 250 piece reel. over operating free-air temperature range (unless otherwise noted) (1) VALUE UNIT VIN, SS/ENA, SYNC –0.3 to 7 V RT –0.3 to 6 V VI Input voltage range VSENSE –0.3 to 4 V BOOT –0.3 to 17 V VBIAS, PWRGD, COMP –0.3 to 7 V VO Output voltage range PH (steady state) –0.6 to 10 V PH (transient < 20 ns) –2 to 10 V PH Internally Limited IO Output current range COMP, VBIAS 6 mA PH 6 A Sink current COMP 6 mA SS/ENA, PWRGD 10 mA Voltage differential AGND to PGND ±0.3 V Continuous power dissipation See Power Dissipation Rating Table TJ Operating virtual junction temperature range –40 to 150 °C Tstg Storage temperature –65 to 150 °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.
