S3882P Datasheet (AUK corp) - Current Mode PWM Controller

S3882P, Current Mode PWM Controller

The S3882 is fixed PWM controller for Off-line and DC-DC converter applications.

The internal circuits include UVLO, low start up current circuit, temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totempole output for driving a power MOSFET.

* Low start up current < 0.3mA

* Operating range up to 500KHz

* Cycle by cycle current limiting

* Under Voltage Lock Out with hysteresis

* Short shutdown delay time ; typical 100nsec

* High current totempole output

* Output swing limiting : 22V
