KA7500B 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 parator, a dead time parator and an oscillator. This device can be operated in the switching frequency of 1kHz to 300kHz.
