JC34063 series
1.5A DC T O DC
CONVERTER CONT ROL
Description
JC34063 series have all the functions required for
DC-to-DC converters: an internal Temperature-
compensated reference, comparator, controlled duty
cycle oscillator with an active current limit circuit,
driver, and high current output switch.
JC34063 series are designed for step-down, step-up
and voltage-inverting applications by using a
minimum number of external components.
For JC34063E can operate for a temperature range
from -40°C to 125°C while JC34063F can operate
from -25°C to 85°C.
