UC3842A規(guī)格書詳情
Description
The UC3842A/UC3843A are fixed PWM controller for Off-Line and DC to 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 totem-pole output for driving a POWER MOSFET. Also UC3842A/ UC3843A provide low start up current below 0.3mA and short shutdown delay time typ. 100ns. The UC3842A has UVLO threshold of 16V(on) and 10V(off). The UC3843A is 8.4V(on) and 7.6V(off). The UC3842A and UC3843A can operate within 100 duty cycle.
Features
? Low Start Current 0.2mA (typ)
? Operating Range Up To 500KHz
? Cycle by Cycle Current Limiting
? Under Voltage Lock Out With Hysteresis
? Short Shutdown Delay Time: typ.100ns
? High Current Totem-pole Output
? Output Swing Limiting: 22V
