DC-to-DC Converter
Control Circuits
The MC34063A Series is a monolithic control circuit containing the
primary functions required for DC鈥搕o鈥揇C converters. These devices consist
of an internal temperature compensated reference, comparator, controlled
duty cycle oscillator with an active current limit circuit, driver and high current
output switch. This series was specifically designed to be incorporated in
Step鈥揇own and Step鈥揢p and Voltage鈥揑nverting applications with a
minimum number of external components. Refer to Application Notes
AN920A/D and AN954/D for additional design information.
