LT3436EFE

3A, 800kHz Step-Up Switching Regulator

Linear Technology 

LT3436

ELECTRICAL CHARACTERISTICS

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The LT3436E is guaranteed to meet performance specifications

from 0°C to 125°C. Specifications over the – 40°C to 125°C operating

junction temperature range are assured by design, characterization and

correlation with statistical process controls.

Note 3: Minimum input voltage is defined as the voltage where the internal

regulator enters lockout. Actual minimum input voltage to maintain a

regulated output will depend on output voltage and load current. See

Applications Information.
