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.
