    Description: The UC3844BN is a high performance current mode pwm

    controller.

    The UC3844BN provides the necessary features to implement

    off-line or DC to DC fixed frequency current mode control schemes with a

    minimal external parts count.

    Internally implemented circuits includea

    trimmed oscillator for precise DUTY CYCLE CONTROL under voltage lock out

    featuring start - up current less than 0.5mA, a precision reference

    trimmed for accuracy at the error ampinput, logic to insure latched

    operation, a PWM comparator which also provides current limit control,

    and a totem pole output stage designed to source or sink high peak

    current.

    The out put stage, suitable for driving N-Channel MOSFETs, is

    low in the offstate.

    The UC3844BN has UVLO thresholds of 16V (on) and

    10V (off), ideally suited off-line applications.

    Parametrics: UC3844BN absolute maximum ratings: (1)Supply Voltage (low impedance source), Vi: 30 V; (2)Supply Voltage (Ii < 30mA), Vi: Self Limiting; (3)Output Current, IO: ±1 A; (4)Output Energy (capacitive load), EO: 5 mJ; (5)Analog Inputs: -0.3 to 5.5 V; (6)Error Amplifier Output Sink Current: 10 mA; (7)Power Dissipation at Tamb ≤ 25 (Minidip), Ptot: 1.25 W; (8)Power Dissipation at Tamb ≤ 25 (SO8), Ptot: 800 mW; (9)Storage Temperature Range, Tstg: -65 to 150; (10)Junction Operating Temperature, TJ: -40 to 150; (11)Lead Temperature (soldering 10s), TL: 300.

    ]UC3844BN features: (1)trimmed oscillator for precise fre-quency control; (2)oscillator frequency guaranteed at 250kHz; (3)current mode operation to 500khz; (4)automatic feed forward compensa-tion; (5)latching pwm for cycle-by-cycle current limiting; (6)internally trimmed reference with undervoltage lockout; (7)high current totempoleoutput; (8)undervoltage lockout with hyster-esis; (9)low start-upandoperatingcurre nt.
