KA3845 Datasheet | Unknown Manufacturer

KA3842/43/44/45 Inv № 59 Current Mode PWM Controller July 1995 - revised July 2002 DESCRIPTION KA3842/43/44/45 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. Protection circuitry includes built undervoltage lockout and current limiting. The UC3842A(AM) and UC3844A(AM) have UVLO thresholds of 16 V (on) and 10 V...
