KA3843規(guī)格書詳情

DESCRIPTION

KA3842/43/44/45 are fixed frequency current mode PWM

controller. They are specially designed for OFF?Line and DC to DC converter applications

with a minimal external components. Internally implemented circuits include 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 ideally

suited for driving a power MOSFET. Protection circuitry includes built undervoltage lockout

and current limiting.

The UC3842A(AM) and UC3844A(AM) have UVLO thresholds of 16 V (on) and 10 V (off).

The corresponding thresholds for the UC3843A(AM)/45A(AM) are 8.4V (on) and 7.6V

(off). The UC3842A(AM) and UC3843A(AM) can operate within 100% duty cycle. The

UC3844A(AM) and UC3845A(AM) can operate within 50% duty cycle.

The UC384XA(AM) has Start-Up Current 0.17mA (typ).

FEATURES

? Low Start-Up and Operating Current

? High Current Totem Pole Output

? Undervoltage Lockout With Hysteresis

? Operating Frequency Up To 300KHz (384XA)

500KHz (384XAM
