KA7500B Datasheet

Voltage-Mode PWM Controller


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. KA7500B 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
