MC34163P

The MC34163P|MC34163DW |MC34163DWG |MC34163DWR2G |MC34163PG is one of The MC34163 series.The MC34163 series are monolithic power switching regulators that contain the primary functions required for dctodc converters. This series is specifically designed to be incorporated in stepup, stepdown, and voltageinverting 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 cyclebycycle current limiting, and internal thermal shutdown. Also included is a low voltage indicator output designed to interface with microprocessor based systems.

Features of the The MC34163 series are:(1)Output Switch Current in Excess of 3.0 A;(2)Operation from 2.5 V to 40 V Input;(3)Low Standby Current;(4)Precision 2% Reference;(5)Controlled Duty Cycle Oscillator;(6)Driver with Bootstrap Capability for Increased Efficiency;(7)CyclebyCycle Current Limiting;(8)Internal Thermal Shutdown Protection;(9)Low Voltage Indicator Output for Direct Microprocessor Interface;(10)Heat Tab Power Package.
