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
DescriptionThe 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.
