Buck / Boost / Inverting Converter, Switching Regulator, 2.5 A

The NCV33163 series are monolithic power Buck Boost Inverting Switching Regulators that contain the primary functions required for dc-to-dc converters. This series is specifically designed to be incorporated in step-up (boost), step-down (buck) 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 Buck Boost Inverting Switching Regulators are contained in a 16 pin dual-in-line heat tab plastic package for improved thermal conduction.
