MC34063 DC TO DC Converter IC DIP-8 Package

The MC34063A Series is a monolithic control circuit containing the primary functions required for DC−to−DC converters. These devices consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. This series was specifically designed to be incorporated in Step−Down and Step−Up and Voltage−Inverting applications with a minimum number of external components. Features:- Operation from 3.0 V to 40 V Input Low Standby Current Current Limiting Output Switch Current to 1.5 A Output Voltage Adjustable Frequency Operation to 100 kHz Precision 2% Reference NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Specification:- Rating Symbol Value Unit Power Supply Voltage VCC 40 Vdc Comparator Input Voltage Range VIR −0.3 to +40 Vdc Switch Collector Voltage VC(switch) 40 Vdc Switch Emitter Voltage (VPin 1 = 40 V) VE(switch) 40 Vdc Switch Collector to Emitter Voltage VCE(switch) 40 Vdc Driver Collector Voltage VC(driver) 40 Vdc Driver Collector Current (Note 1) IC(driver) 100 mA Switch Current ISW 1.5 A Power Dissipation TA = 25°C PD 1.25 W Operating Junction Temperature Tj 150 °C Operating Ambient Temperature Range Ta 0 to +70 °C Storage Temperature Range Tstg −65 to +150 °C Related Document:- MC34063 IC Data Sheet
