Description
GM34063 has all the functions required for DC-to-DC
converters: an internal temperature- compensated ref-
erence, comparator, controlled duty cycle oscillator
with an active current limit circuit, driver, and high-
current output switch.
GM34063 is designed for step-down, step-up and volt-
age-inverting applications by using a minimum number
of external components.
