These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 7 Specifications 7.1 Absolute Maximum Ratings (1) MIN MAX UNIT VIN, EN/UVLO, VISNS, VOSNS, ISNS(+), ISNS(–) –0.3 60 V BIAS –0.3 40 FB, SS, DITH, RT/SYNC, SLOPE, COMP –0.3 3.6 SW1, SW2 –1 60 SW1, SW2 (20 ns transient) –5.0 65 VCC, MODE, PGOOD –0.3 8.5 LDRV1, LDRV2 –0.3 8.5 BOOT1, HDRV1 with respect to SW1 –0.3 8.5 BOOT2, HDRV2 with respect to SW2 –0.3 8.5 BOOT1, BOOT2 –0.3 68 ISNS(+) with respect to ISNS(-) -0.3 0.3 CS, CSG –0.3 0.3 Operating junction temperature –40 150 °C Storage temperature, Tstg -65 150 (1) Electrostatic discharge (ESD) to measure device sensitivity and immunity to damage caused by assembly line electrostatic discharges into the device. (2) Level listed above is the passing level per ANSI/ESDA/JEDEC JS-001. JEDEC document JEP155 states that 500 V HBM allows safe manufacturing with a standard ESD control process. (3) Level listed above is the passing level per EIA-JEDEC JESD22-C101. JEDEC document JEP157 states that 250 V CDM allows safe manufacturing with a standard ESD control process. 7.2 ESD Ratings VALUE UNIT VESD (1) Human body model (HBM) ESD stress voltage(2) ±2000 V Charged device model (CDM) ESD stress voltage(3) ±750 (1) Recommended Operating Conditions are conditions under the device is intended to be functional. For specifications and test conditions, see Electrical Characteristics . (2) High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C. 7.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) (1) MIN NOM MAX UNIT VIN Input bias voltage 4.2 55 V VISNS Input power stage voltage with external bias (BIAS ≥ 5 V or VIN ≥ 4.5 V) 2.5 55 BIAS Bias supply voltage range (when VCC in regulation) 8 36 VOSNS Output voltage range 0.8 55 EN/UVLO Enable voltage range 0 55 ISNS(+), ISNS(-) Average current sense common mode range 0 55 TJ Operating temperature range(2) –40 125 °C Fsw Operating frequency range 100 600 kHz |
