MIK3842A, MIK3843A MIK3844A, MIK3845A CURRENT MODE PWM CONTROLLER Description MIK3842A, MIK3843A, MIK3844A and MIK3845A are high performance with fixed frequency current mode PWM controllers. They are specially designed for off-Line and DC-to-DC converter applications with minimum external components. These devices feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totem pole output which is suitable for driving MOSFETs. The under voltage lock-out (U.V.L.O.) is designed to operated with 0.17mA typ. start-up current, allowing an efficient bootstrap supply voltage design. The U.V.L.O.
