KA7500B[SMPS Controller]

other part :KA7500   KA7500BD  

Description
The KA7500B is used for the control circuit of the PWM switching regulator. The KA7500B consists of 5V reference voltage circuit, two error amplifiers, a 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.

Features
• Internal Regulator Provides a Stable 5V Reference Supply
   Trimmed to 5%
• 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
