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 16...
