KA7500C  
SMPS Controller  
Features  
Description  
• Internal Regulator Provides a Stable 5V Reference Supply  
Trimmed to ±1% Accuracy.  
• Uncommitted Output TR for 200mA Sink or Source  
Current  
• Output Control for Push-Pull or Single-Ended Operation  
Variable Duty Cycle by Dead Time Control (Pin 4)  
Complete PWM Control Circuit  
• On-Chip Oscillator With Master or Slave Operation  
• Internal Circuit Prohibits Double Pulse at Either Output  
The KA7500C is used for the control circuit of the pulse  
width modulation switching regulator. The KA7500C  
consists of 5V reference voltage circuit, two error amplifiers,  
flip flop, an output control circuit, a PWM comparator, a  
dead time comparator and an oscillator. This device can be  
operated in the switching frequency of 1kHz to 300kHz. The  
precision of voltage reference (Vref) is improved up to ±1%  
with trimming. This provides a better output voltage  
regulation. The operating temperature range is  
-25°C ~ +85°C.
