S3843P

Current Mode PWM Controller

Descriptions

The S3843 is fixed Current PWM controller for Off-line and DC-DC converter applications.

The internal 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 for driving a power MOSFET. Protection circuitly

includes built in under voltage lockout and current limiting. S3843 have UVLO threshold of

8.4V(on) and 7.6V(off). S3843 can operate within 100% duty cycle.
