SNVSAA7A – DECEMBER 2015 – REVISED MAY 2016 LM53625/35-Q1, 2.5-A or 3.5-A, 36-V Synchronous, 2.1-MHz, Step-Down DC-DC Converter
1 Features 3 Description The LM53625-Q1/LM53635-Q1 synchronous buck
regulator is optimized for automotive applications,
providing an output voltage of 5 V, 3.3 V, or an
adjustable output. Advanced high-speed circuitry
allows the LM53625-Q1/LM53635-Q1 to regulate
from an input of 18 V to an output of 3.3 V at a fixed
frequency of 2.1 MHz. Innovative architecture allows
this device to regulate a 3.3-V output from an input
voltage of only 3.55 V. All aspects of the LM53625Q1/LM53635-Q1 are optimized for automotive and
performance-driven industrial customers. An input
voltage range up to 36 V, with transient tolerance up
to 42 V, eases input surge protection design. The
automotive-qualified Hotrod QFN package with
wettable flanks reduces parasitic inductance and
resistance while increasing efficiency, minimizing
switch node ringing, and dramatically lowering …
