General Description
The APW34063 is a monolithic control circuit containing
the primary functions required for DC-to-DC converters.
This device consists of an internal temperature
compensated reference, comparator, controlled duty
cycle oscillator with an active current limit circuit, driver
and high current output switch. This device was
specifically designed to be incorporated in Step-Down
and Step-Up and Voltage-Inverting applications with a
minimum number of external components.
