GL34063
1.5A DC-TO-DC CONVERTER CONTROL CIRCUIT
Description
GL34063 has all the functions required for DC-to-DC
converters: an internal temperature- compensated ref-
erence, comparator, controlled duty cycle oscillator wi-
th an active current limit circuit, driver, and high-
current output switch.
GL34063 is designed for step-down, step-up and vol-
tage-inverting applications by using a minimum num-
ber of external components.
