KA3842AC規(guī)格書詳情

Description

The KA3842AC/KA3842AE are fixed PWM controllers for Off Line and DC to DC converter applications. The internal circuits include UVLO, low start up current, temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totem pole output for driving a POWER MOSFET. Also KA3842AC/KA3842AE provides low start up current below 0.3mA and short shutdown delay time, typically 100ns. The KA3842AC/KA3842AE has a UVLO threshold of 16V(on) and 10V(off). The KA3842AC/KA3842AE can operate within a 100 duty cycle.

Features

■ Low start current 0.2mA (Typ.)

■ Operating range up to 500kHz

■ Cycle by cycle current limiting

■ Under Voltage Lock Out (UVLO) with hysteresis

■ Short shutdown delay time: Typ.100ns

■ High current totem-pole output

■ Output swing limiting: 22V
