FAIRCHILD SEMICONDUCTOR KA3843B 控制器, PWM, 25V-12V电源, 500 kHz, 5V/200mA输出, DIP-8
The is a fixed frequency current-mode PWM Controller for off-line and DC-to-DC converter applications with minimum external components. This integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator and a high current totem pole output ideally suited for driving a power MOSFET. The KA3843B is 8.5V on and 7.9V off and it can operate within 100% duty cycle.
