The 2842/43/44/45 are fixed frequency current mode PWM controller.
They are specially designed for OFF−Line and DC to DC converter applications with a minimal external ponents.
Internally implemented circuits include a trimmed oscillator for precise duty cycle control, a temperature pensated reference, high gain error amplifier, current sensing parator, and a high current totempole output ideally suited for driving a power MOSFET.
