JC34063 Datasheet | Unknown Manufacturer

JC34063 series Description JC34063 series have all the functions required for DC-to-DC converters: an internal Temperaturepensated reference, parator, controlled duty cycle oscillator with an active current limit circuit, driver, and high current output switch. JC34063 series are designed for step-down, step-up and voltage-inverting applications by using a minimum number of external ponents. For JC34063E can operate for a temperature range from -40°C to 125°C while JC34063F can operate from -25°C to 85°C. 1.5A DC T O DC CONVERTER CONT ROL Features ‹ ‹ ‹ ‹ ‹ ‹ 3.0V to 40V Input Adjustable Output Voltage Output Switch Current to 1.5A Low Standby Current Operating Frequency to 100k Hz Precision 1 % Reference available Application z CD-ROM z Motherboards z z Battery Chargers z DSL Modem SMPS Power Supply Schematic Diagram 8 Driver Collector S Q R 7 IPK Sense IPK Oscillator CT 6 VCC parator + 5 parator Inverting Inpu t 1.25V VREF 100 Q2 Q1 1 Switch Collector 2 Switch Em itter 3 Timing Cap acitor 4 GND JC34063V2.02 1 http://..
