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 1)
Junction-to-Ambient Thermal Resistance (qJA)...............48°C/W
Junction-to-Case Thermal Resistance (qJC)......................7°C/W
Note 1: 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
(VIN = 12V (for the MAX17595, bring VIN up to 21V for startup), VCS = VSLOPE = VDITHER = VFB = VOVI = VSGND = VPGND = 0V,
VEN/UVLO = +2V; NDRV, SS, COMP are unconnected, RRT = 25kΩ, CVIN = 1µF, CVDRV = 1µF, TA = TJ = -40°C to +125°C, unless
otherwise noted. Typical values are at TA = TJ = +25°C.) (Note 2)
