POWER SWITCHING REGULATORS    开关电源 切换 (DC/DC) 转换器和控制器

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.
