Inverting Switching
Regulators
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.
