AX6203   High Performance, Current Mode, Switching Power Supply Controller
性能描述：
      The AX6203 is a high performance, current mode control PWM controller, specific designed forAC/DC transformer with high  cost performance ratio. It provides continuous output power 12W andpeak output power 18W at the input voltage range 85V~265V. Its optimized and highly reasonablecircuit design has made it possible to minimize the total cost of the product.  This switching powersupply controller could be applied to t*ical flyback circuit *ology to constitute a simple AC/DCconverter.
      The initial circuit of AX6203 has been designed with a unique current sink method to startup thesystem by using the magnification function of the switching transistor itself. This will significantlyreduce the power consumption of the start-up resistor. While output power becomes *aller, AX6203will automatically lower the operating frequency to achieve very *all standby power consumption.When the switching transistor cuts off, the internal circuit will bias it reversely, it helps to improvethe resistant voltage over 700V high voltage of OC pin. This will ensure the safety of the switchingtransistor.  
      The AX6203 provides overload and saturation prevention functions, capable of preventing  disorders such  as  overload, transformersaturation and output short circuit, in order to increase the reliability of the power supply. The AX6203 also provides an accurate reference voltage 2.5V for clockgeneration circuit, and the clock frequency may be set by an external capacitor. Presently, standardPDIP-8L package and environmental friendly lead-free package in compliance with European standardare supplied.
特点：
• Built-in 700V high voltage switching transistor, to minimize external components
• Latched PWM and pulse-by-pulse current limit inspection
• Reduced frequency at low output power, standby power consumption below 0.3W
• Built-in slope and feedback compensation function
• Independent the upper limit current inspection controller, real time to handle overload and over current function
• Turn off the periodic bias output of the emitter, to improve the sustaining voltage
• Built-in  current  limit  resistor  with  temperature  compensation  to  control  the  current limit accuray

• Built-in thermal protection function
• Complete  start-up by using magnification function of switching transistor, to  reduce the power consumption of start-up resistor more than ten times
• Automatic VCC over-voltage limit
• Wide continuous output power up to 12W and peak output power up to 18W
• Available in the PDIP-8L Pb-Free Package
