S3842
Current Mode PWM Controller
Descriptions
The S3842, high performance current mode controller, Provides the necessary features to
off-line and DC-DC fixed frequency current control applications offering the designer a cost
effective solution with minimal external components. Internally protection circuity includes
built-in input and reference under-voltage lockout and current limiting with hysteresis.
Also other characteristics of internal circuit provide improved line regulation, enhanced load
response, trimmed oscillation for precise duty cycle control, a temperature compensated
reference, high gain error amplifier, current sensing comparator and totempole output
designed to source and sink high peak current from a capacitive load such as the gate of a
power MOSFET.
Features
Optimized for off-line control
Current mode operation to 500
Low start up and operating current
Under voltage lockout with 6V hysteresis
Pulse by pulse current limiting
Internally trimmed bandgap reference about 5V
Enhanced load response characteristic
Automatic feed forward compensation
Ordering
