MT34063

MT34063 Universal DC to DC Converter ‹ DESCRIPTION The MT34063 is designed for the applications which require DC - DC converters. It can be operated in a wide input range from 3.0V to 40V and has the controlled duty cycle oscillator, driver and high current output switch. Also, with the internal temperature compensation circuit, the MT34063 provides an internally trimmed precision 2% reference voltage of 1.25V. These features make the MT34063 suitable for step-up, step-down and voltage–inverting applications. The M34063 is available in the 8-Pin Plastic SOIC and 8-Pin Plastic DIP packages. ‹ ¾ ¾ ¾ ¾ ¾ ¾ ¾ FEATURES Output switch current up to 1.5A Wide supply voltage range 3.0V to 40V 100kHz operational frequency Low standby current Adjustable Output Voltage Internally trimmed 2% 1.25V Reference Voltage Direct pin-to-pin replacement for industrial product MC34063A. ‹ ¾ ¾ ¾ APPLICATIONS Adaptors Battery chargers Mother Board ‹ PIN CONFIGURATIONS SOP-8 (Top View) DIP-8 (Top View) MT34063M MT34063T -1- www.matrix-microtech.com.tw Free Datasheet http://www.datasheet4u.net/ MT34063 Universal DC to DC Converter ‹ BLOCK DIAGRAM Pin Assignment Descriptions Pin 1 : SC - Switch Collector Pin Pin 2 : SE - Switch Emitter Pin 3 : Cap - Oscillator Timing Capacitor Pin 4 : GND - Ground Pin 8 : DrC- Driver Collector Pin 7 : ISEN- I Peak Sense Pin 6 : VCC- Power Supply Pin 5 : VFB- Comparator inverting input ‹ ABSOLUTE MAXIMUM RATINGS Parameter Supply voltage Thermal resistance ...
