OUT............................................................... -0.3V to V_IN + 0.3V
HVEN (Note 1).............................................. -0.3V to V_IN + 0.3V
GP......................................max (-0.3V, V_IN - 20V) to V_IN + 0.3V
UVLO, OVLO................................-0.3V to min (V_IN + 0.3V, 20V)
FLAG, EN, RIPEN, CLTS1, CLTS2..........................-0.3V to +6V
Maximum Current into IN (DC) (Note 2)..................................6A
SETI...............................................-0.3V to min (V_IN + 0.3V, 6V)
Continuous Power Dissipation (T_A = +70ºC)
TQFN (derate 34.5mW/ºC above +70ºC)...................2758mW
Operating Temperature Range...........................-40ºC to +125ºC
Junction Temperature....................................................... +150ºC
Storage Temperature Range..............................-65ºC to +150°C

Note 1: An external pFET or diode is required to achieve negative input protection.
Note 2: DC current-limited by R_SETI, as well as by thermal design.
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 in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
Package Thermal Characteristics (Note 3)
TQFN
Junction-to-Ambient Thermal Resistance (θ_JA)...........29°C/W
Junction-to-Case Thermal Resistance (θ_JC)..................2°C/W
Note 3: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
Electrical Characteristics
(V_IN = 5.5V to 58V, T_A = -40°C to +125°C, unless otherwise noted. Typical values are at V_IN = 12V, T_A = +25°C) (Note 4)
