LTC4412HVIS6
TJMAX = 125°C, θJA = 230°C/W
The q denotes specifications which apply over the full operating
temperature range, unless otherwise noted specifications are at TA = 25°C, VIN = 12V, CTL and GND = 0V. Current into a pin is positive
and current out of a pin is negative. All voltages are referenced to GND, unless otherwise specified.
Consult LTC Marketing for parts specified with wider operating temperature ranges.
