Absolute Maximum Ratings
(All voltages referenced to GND.)
IN (Note 1)..............................................................-0.3V to +29V
OUT............................................................... -0.3V to V_IN + 0.3V
OVLO.....................................................................-0.3V to +24V
ACOK.......................................................................-0.3V to +6V
Continuous IN, OUT Current.................................................4.5A
(NOTE: Continuous current limited by thermal design)
Peak IN, OUT Current (10ms)..................................................8A
Continuous Power Dissipation (T_A = +70ºC)
WLP (derate 13.7mW/ºC above +70ºC).....................1096mW
Operating Temperature Range.............................-40ºC to +85ºC
Junction Temperature....................................................... +150ºC
Storage Temperature Range..............................-65ºC to +150ºC
Soldering Temperature (reflow)........................................ +260ºC
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 2)
WLP
Junction-to-Ambient Thermal Resistance (θ_JA)...........73°C/W
Note 1: Survives burst pulse up to 80V with 2Ω series resistance.
Note 2: 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 = +2.5V to +28V, C_IN = 0.1μF, T_A = -40ºC to +85ºC, unless otherwise noted. Typical values are at V_IN = +5.0V, I_IN ≤ 3A, and
T_A = +25ºC.) (Note 3)
