8 Specifications 8.1 Absolute Maximum Ratings
Over the recommended operating junction temperature range of –40°C to +150°C , unless otherwise noted(1)
MIN MAX UNIT
VIN –0.3 32 Input voltage EN –0.3 6 FB –0.3 6 SW, DC –0.3 32 SW, transient < 10 ns –3 33 V BST –0.3 SW + 6 Output voltage BST–SW –0.3 6 SS/PG –0.3 6 RT –0.3 6 TJ Operating junction temperature(2) –40 150 °C Tstg Storage temperature –65 150 (1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime. (2) Operating at junction temperatures greater than 150°C, although possible, degrades the lifetime of the device.
8.2 ESD Ratings VALUE UNIT
Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 V(ESD) Electrostatic discharge V Charged device model (CDM), per ANSI/ESDA/JEDEC JS-002, all pins(2) ±500 (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
8.3 Recommended Operating Conditions
Over the recommended operating junction temperature range of –40°C to +150°C, unless otherwise noted(1)
MIN NOM MAX UNIT
VIN 3.8 30 EN –0.1 5.5 Input voltage FB –0.1 5.5 PG –0.1 5.5 VOUT 0.8 22 V SW, DC –0.1 30 Output voltage SW, transient < 10 ns –3 32 BST –0.1 SW + 5.5 BST-SW –0.1 5.5 TPS62933, TPS62933x 0 3 Ouput current IOUT A TPS62932 0 2 Temperature Operating junction temperature, TJ –40 150 °C (1) The Recommended Operating Conditions indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits.
