The MC34163 series are monolithic power switching regulators that
contain the primary functions required for dc ? to ? dc converters. This
series is specifically designed to be incorporated in step ? up,
step ? down, and voltage ? inverting applications with a minimum
number of external components.
These devices consist of two high gain voltage feedback
comparators, temperature compensated reference, controlled duty
cycle oscillator, driver with bootstrap capability for increased
efficiency, and a high current output switch. Protective features consist
of cycle ? by ? cycle current limiting, and internal thermal shutdown.
Also included is a low voltage indicator output designed to interface
with microprocessor based systems.
These devices are contained in a 16 pin dual ? in ? line heat tab plastic
package for improved thermal conduction.
