MIK3845A - CURRENT MODE PWM CONTROLLER

Download the MIK3845A datasheet PDF. This datasheet also covers the MIK3842A variant, as both devices belong to the same current mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features

  • Low Start-Up and Operating Current.
  • Automatic Feed Forward Compensation.
  • Current Mode Operating Frequency up to 500KHz.
  • Trimmed Oscillator Discharge Current for Precise Duty Cycle Control.

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.
