www.DataSheet4U.com TMC TD3842A / 3843A / 3844A / 3845A HIGH PERFORMANCE CURRENT MODE PWM CONTROLLERS DESCRIPTION The TD3842A / 3843A/384 4A/3845A are fixed frequency current-mode PWM controller. They are specially designed for Off - Line and DC-to-DC converter applications with minimum external components. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier. current sensing comparator, and a high current totempole output Ideally suited for driving a power MOSFET. Protection circuity Includes built in under-voltage lockout and current limiting. The TD3842A and TD3844A have UVLO thresholds of 16V (on) and 10V (off) The TD 3843A and TD3845A are 8.4V (on) and 7.
