DESCRIPTION
The IP34063 series of control circuits contains all the functions required to implement DC–DC converters. Included are internal voltage reference, comparator, controlled duty cycle oscillator with current limit circuit, driver, and high current output switch. This series was specifically designed to be incorporated in Step-Down (Buck) and Step-Up (Boost) applications with a minimum number of external components.
