    DESCRIPTION/ORDERING INFORMATION  
    The TL284xB and TL384xB series of control integrated circuits provide the features that are necessary to  
    implement off-line or dc-to-dc fixed-frequency current-mode control schemes, with a minimum number of  
    external components. Internally implemented circuits include an undervoltage lockout (UVLO) and a precision  
    reference that is trimmed for accuracy at the error amplifier input. Other internal circuits include logic to ensure  
    latched operation, a pulse-width modulation (PWM) comparator that also provides current-limit control, and a  
    totem-pole output stage designed to source or sink high-peak current. The output stage, suitable for driving  
    N-channel MOSFETs, is low when it is in the off state.  
    The TL284xB and TL384xB series are pin compatible with the standard TL284x and TL384x with the following  
    improvements. The start-up current is specified to be 0.5 mA (max), while the oscillator discharge current is  
    trimmed to 8.3 mA (typ). In addition, during undervoltage lockout conditions, the output has a maximum  
    saturation voltage of 1.2 V while sinking 10 mA (VCC = 5 V).  
    Major differences between members of these series are the UVLO thresholds and maximum duty-cycle ranges.  
    Typical UVLO thresholds of 16 V (on) and 10 V (off) on the TLx842B and TLx844B devices make them ideally  
    suited to off-line applications. The corresponding typical thresholds for the TLx843B and TLx845B devices are  
    8.4 V (on) and 7.6 V (off). The TLx842B and TLx843B devices can operate to duty cycles approaching 100%. A  
    duty-cycle range of 0% to 50% is obtained by the TLx844B and TLx845B by the addition of an internal toggle  
    flip-flop, which blanks the output off every other clock cycle.The TL284xB-series devices are characterized for  
    operation from –40°C to 85°C. The TL384xB-series devices are characterized for operation from 0°C to 70°C.

    (1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings  
    only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating  
    conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.  
    (2) All voltages are with respect to the device GND terminal.  
    (3) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient  
    temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability.  
    (4) The package thermal impedance is calculated in accordance with JESD 51-7.

    Open-Loop Laboratory Test Fixture  
    In the open-loop laboratory test fixture (see Figure 4), high peak currents associated with loads necessitate  
    careful grounding techniques. Timing and bypass capacitors should be connected close to the GND terminal in a  
    single-point ground. The transistor and 5-kΩ potentiometer sample the oscillator waveform and apply an  
    adjustable ramp to the ISENSE terminal.

    APPLICATION INFORMATION (continued)  
    Shutdown Technique  
    The PWM controller (see Figure 5) can be shut down by two methods: either raise the voltage at ISENSE above  
    1 V or pull the COMP terminal below a voltage two diode drops above ground. Either method causes the output  
    of the PWM comparator to be high (refer to block diagram). The PWM latch is reset dominant so that the output  
    remains low until the next clock cycle after the shutdown condition at the COMP or ISENSE terminal is removed.  
    In one example, an externally latched shutdown can be accomplished by adding an SCR that resets by cycling  
    VCC below the lower UVLO threshold. At this point, the reference turns off, allowing the SCR to reset.

    A fraction of the oscillator ramp can be summed resistively with the current-sense signal to provide slope  
    compensation for converters requiring duty cycles over 50% (see Figure 6). Note that capacitor C forms a filter  
    with R2 to suppress the leading-edge switch spikes.

    Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check  
    http://www.ti.com/productcontent for the latest availability information and additional product content details.  
    TBD: The Pb-Free/Green conversion plan has not been defined.  
    Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
    for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
    at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
    Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
