MPQ8875A – 36V, 4-SWITCH SYNC BUCK-BOOST CONVERTER WITH I²C, AEC-Q100

ELECTRICAL CHARACTERISTICS

Typical values are at V_IN= 12V, V_EN= 2V, T_J= 25°C, all voltages with respect to ground, unless

otherwise noted. Minimum and maximum values are at V_IN= 12V, V_EN= 2V, T_J= -40°C to +150°C,

all voltages with respect to ground, guaranteed by characterization, unless otherwise noted.
