The MC34063A is a monolithic control circuit containing
the primary functions required for DC-to-DC converters.
The device consists of an internal temperature compen-
sated reference, comparator, controlled duty cycle oscill-
ator with an active current limit circuit, driver and high
current output switch. MC34063A is specifically designed
to be incorporated in Step-Down, Step-Up and Voltage-
Inverting applications with a minimum number of extern-
al components.
