The MC33163 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.

Key Features:

• Output Switch Current in Excess of 3.0 A
• Operation from 2.5 V to 40 V Input
• Low Standby Current
• Precision 2% Reference
• Controlled Duty Cycle Oscillator
• Driver with Bootstrap Capability for Increased Efficiency
