Power Switching Regulators
GENERAL DESCRIPTION
The TC33163 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, con-
trolled 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 micropro-
cessor based systems. These devices are contained in a
16-Pin dual-in-line heat tab plastic package for improved
thermal conduction.
